-version of ksymoops to decode the report; see REPORTING-BUGS in the
-root of the Linux source for more information.
+If the unthinkable happens and your kernel oopses, you may need the
+ksymoops tool to decode it, but in most cases you don't.
+In the 2.6 kernel it is generally preferred to build the kernel with
+CONFIG_KALLSYMS so that it produces readable dumps that can be used as-is
+(this also produces better output than ksymoops).
+If for some reason your kernel is not build with CONFIG_KALLSYMS and
+you have no way to rebuild and reproduce the Oops with that option, then
+you can still decode that Oops with ksymoops.

+RCU-based dcache locking model
+==============================
+
+On many workloads, the most common operation on dcache is to look up a
+dentry, given a parent dentry and the name of the child. Typically,
+for every open(), stat() etc., the dentry corresponding to the
+pathname will be looked up by walking the tree starting with the first
+component of the pathname and using that dentry along with the next
+component to look up the next level and so on. Since it is a frequent
+operation for workloads like multiuser environments and web servers,
+it is important to optimize this path.
+
+Prior to 2.5.10, dcache_lock was acquired in d_lookup and thus in
+every component during path look-up. Since 2.5.10 onwards, fast-walk
+algorithm changed this by holding the dcache_lock at the beginning and
+walking as many cached path component dentries as possible. This
+significantly decreases the number of acquisition of
+dcache_lock. However it also increases the lock hold time
+significantly and affects performance in large SMP machines. Since
+2.5.62 kernel, dcache has been using a new locking model that uses RCU
+to make dcache look-up lock-free.
+
+The current dcache locking model is not very different from the
+existing dcache locking model. Prior to 2.5.62 kernel, dcache_lock
+protected the hash chain, d_child, d_alias, d_lru lists as well as
+d_inode and several other things like mount look-up. RCU-based changes
+affect only the way the hash chain is protected. For everything else
+the dcache_lock must be taken for both traversing as well as
+updating. The hash chain updates too take the dcache_lock. The
+significant change is the way d_lookup traverses the hash chain, it
+doesn't acquire the dcache_lock for this and rely on RCU to ensure
+that the dentry has not been *freed*.
+
+
+Dcache locking details
+======================
+
+For many multi-user workloads, open() and stat() on files are very
+frequently occurring operations. Both involve walking of path names to
+find the dentry corresponding to the concerned file. In 2.4 kernel,
+dcache_lock was held during look-up of each path component. Contention
+and cache-line bouncing of this global lock caused significant
+scalability problems. With the introduction of RCU in Linux kernel,
+this was worked around by making the look-up of path components during
+path walking lock-free.
+
+
+Safe lock-free look-up of dcache hash table
+===========================================
+
+Dcache is a complex data structure with the hash table entries also
+linked together in other lists. In 2.4 kernel, dcache_lock protected
+all the lists. We applied RCU only on hash chain walking. The rest of
+the lists are still protected by dcache_lock. Some of the important
+changes are :
+
+1. The deletion from hash chain is done using hlist_del_rcu() macro
+ which doesn't initialize next pointer of the deleted dentry and
+ this allows us to walk safely lock-free while a deletion is
+ happening.
+
+2. Insertion of a dentry into the hash table is done using
+ hlist_add_head_rcu() which take care of ordering the writes - the
+ writes to the dentry must be visible before the dentry is
+ inserted. This works in conjunction with hlist_for_each_rcu() while
+ walking the hash chain. The only requirement is that all
+ initialization to the dentry must be done before
+ hlist_add_head_rcu() since we don't have dcache_lock protection
+ while traversing the hash chain. This isn't different from the
+ existing code.
+
+3. The dentry looked up without holding dcache_lock by cannot be
+ returned for walking if it is unhashed. It then may have a NULL
+ d_inode or other bogosity since RCU doesn't protect the other
+ fields in the dentry. We therefore use a flag DCACHE_UNHASHED to
+ indicate unhashed dentries and use this in conjunction with a
+ per-dentry lock (d_lock). Once looked up without the dcache_lock,
+ we acquire the per-dentry lock (d_lock) and check if the dentry is
+ unhashed. If so, the look-up is failed. If not, the reference count
+ of the dentry is increased and the dentry is returned.
+
+4. Once a dentry is looked up, it must be ensured during the path walk
+ for that component it doesn't go away. In pre-2.5.10 code, this was
+ done holding a reference to the dentry. dcache_rcu does the same.
+ In some sense, dcache_rcu path walking looks like the pre-2.5.10
+ version.
+
+5. All dentry hash chain updates must take the dcache_lock as well as
+ the per-dentry lock in that order. dput() does this to ensure that
+ a dentry that has just been looked up in another CPU doesn't get
+ deleted before dget() can be done on it.
+
+6. There are several ways to do reference counting of RCU protected
+ objects. One such example is in ipv4 route cache where deferred
+ freeing (using call_rcu()) is done as soon as the reference count
+ goes to zero. This cannot be done in the case of dentries because
+ tearing down of dentries require blocking (dentry_iput()) which
+ isn't supported from RCU callbacks. Instead, tearing down of
+ dentries happen synchronously in dput(), but actual freeing happens
+ later when RCU grace period is over. This allows safe lock-free
+ walking of the hash chains, but a matched dentry may have been
+ partially torn down. The checking of DCACHE_UNHASHED flag with
+ d_lock held detects such dentries and prevents them from being
+ returned from look-up.
+
+
+Maintaining POSIX rename semantics
+==================================
+
+Since look-up of dentries is lock-free, it can race against a
+concurrent rename operation. For example, during rename of file A to
+B, look-up of either A or B must succeed. So, if look-up of B happens
+after A has been removed from the hash chain but not added to the new
+hash chain, it may fail. Also, a comparison while the name is being
+written concurrently by a rename may result in false positive matches
+violating rename semantics. Issues related to race with rename are
+handled as described below :
+
+1. Look-up can be done in two ways - d_lookup() which is safe from
+ simultaneous renames and __d_lookup() which is not. If
+ __d_lookup() fails, it must be followed up by a d_lookup() to
+ correctly determine whether a dentry is in the hash table or
+ not. d_lookup() protects look-ups using a sequence lock
+ (rename_lock).
+
+2. The name associated with a dentry (d_name) may be changed if a
+ rename is allowed to happen simultaneously. To avoid memcmp() in
+ __d_lookup() go out of bounds due to a rename and false positive
+ comparison, the name comparison is done while holding the
+ per-dentry lock. This prevents concurrent renames during this
+ operation.
+
+3. Hash table walking during look-up may move to a different bucket as
+ the current dentry is moved to a different bucket due to rename.
+ But we use hlists in dcache hash table and they are
+ null-terminated. So, even if a dentry moves to a different bucket,
+ hash chain walk will terminate. [with a list_head list, it may not
+ since termination is when the list_head in the original bucket is
+ reached]. Since we redo the d_parent check and compare name while
+ holding d_lock, lock-free look-up will not race against d_move().
+
+4. There can be a theoretical race when a dentry keeps coming back to
+ original bucket due to double moves. Due to this look-up may
+ consider that it has never moved and can end up in a infinite loop.
+ But this is not any worse that theoretical livelocks we already
+ have in the kernel.
+
+
+Important guidelines for filesystem developers related to dcache_rcu
+====================================================================
+
+1. Existing dcache interfaces (pre-2.5.62) exported to filesystem
+ don't change. Only dcache internal implementation changes. However
+ filesystems *must not* delete from the dentry hash chains directly
+ using the list macros like allowed earlier. They must use dcache
+ APIs like d_drop() or __d_drop() depending on the situation.
+
+2. d_flags is now protected by a per-dentry lock (d_lock). All access
+ to d_flags must be protected by it.
+
+3. For a hashed dentry, checking of d_count needs to be protected by
+ d_lock.

+ramfs, rootfs and initramfs
+October 17, 2005
+Rob Landley <rob@landley.net>
+=============================
+
+What is ramfs?
+--------------
+
+Ramfs is a very simple filesystem that exports Linux's disk caching
+mechanisms (the page cache and dentry cache) as a dynamically resizable
+ram-based filesystem.
+
+Normally all files are cached in memory by Linux. Pages of data read from
+backing store (usually the block device the filesystem is mounted on) are kept
+around in case it's needed again, but marked as clean (freeable) in case the
+Virtual Memory system needs the memory for something else. Similarly, data
+written to files is marked clean as soon as it has been written to backing
+store, but kept around for caching purposes until the VM reallocates the
+memory. A similar mechanism (the dentry cache) greatly speeds up access to
+directories.
+
+With ramfs, there is no backing store. Files written into ramfs allocate
+dentries and page cache as usual, but there's nowhere to write them to.
+This means the pages are never marked clean, so they can't be freed by the
+VM when it's looking to recycle memory.
+
+The amount of code required to implement ramfs is tiny, because all the
+work is done by the existing Linux caching infrastructure. Basically,
+you're mounting the disk cache as a filesystem. Because of this, ramfs is not
+an optional component removable via menuconfig, since there would be negligible
+space savings.
+
+ramfs and ramdisk:
+------------------
+
+The older "ram disk" mechanism created a synthetic block device out of
+an area of ram and used it as backing store for a filesystem. This block
+device was of fixed size, so the filesystem mounted on it was of fixed
+size. Using a ram disk also required unnecessarily copying memory from the
+fake block device into the page cache (and copying changes back out), as well
+as creating and destroying dentries. Plus it needed a filesystem driver
+(such as ext2) to format and interpret this data.
+
+Compared to ramfs, this wastes memory (and memory bus bandwidth), creates
+unnecessary work for the CPU, and pollutes the CPU caches. (There are tricks
+to avoid this copying by playing with the page tables, but they're unpleasantly
+complicated and turn out to be about as expensive as the copying anyway.)
+More to the point, all the work ramfs is doing has to happen _anyway_,
+since all file access goes through the page and dentry caches. The ram
+disk is simply unnecessary, ramfs is internally much simpler.
+
+Another reason ramdisks are semi-obsolete is that the introduction of
+loopback devices offered a more flexible and convenient way to create
+synthetic block devices, now from files instead of from chunks of memory.
+See losetup (8) for details.
+
+ramfs and tmpfs:
+----------------
+
+One downside of ramfs is you can keep writing data into it until you fill
+up all memory, and the VM can't free it because the VM thinks that files
+should get written to backing store (rather than swap space), but ramfs hasn't
+got any backing store. Because of this, only root (or a trusted user) should
+be allowed write access to a ramfs mount.
+
+A ramfs derivative called tmpfs was created to add size limits, and the ability
+to write the data to swap space. Normal users can be allowed write access to
+tmpfs mounts. See Documentation/filesystems/tmpfs.txt for more information.
+
+What is rootfs?
+---------------
+
+Rootfs is a special instance of ramfs, which is always present in 2.6 systems.
+(It's used internally as the starting and stopping point for searches of the
+kernel's doubly-linked list of mount points.)
+
+Most systems just mount another filesystem over it and ignore it. The
+amount of space an empty instance of ramfs takes up is tiny.
+
+What is initramfs?
+------------------
+
+All 2.6 Linux kernels contain a gzipped "cpio" format archive, which is
+extracted into rootfs when the kernel boots up. After extracting, the kernel
+checks to see if rootfs contains a file "init", and if so it executes it as PID
+1. If found, this init process is responsible for bringing the system the
+rest of the way up, including locating and mounting the real root device (if
+any). If rootfs does not contain an init program after the embedded cpio
+archive is extracted into it, the kernel will fall through to the older code
+to locate and mount a root partition, then exec some variant of /sbin/init
+out of that.
+
+All this differs from the old initrd in several ways:
+
+ - The old initrd was a separate file, while the initramfs archive is linked
+ into the linux kernel image. (The directory linux-*/usr is devoted to
+ generating this archive during the build.)
+
+ - The old initrd file was a gzipped filesystem image (in some file format,
+ such as ext2, that had to be built into the kernel), while the new
+ initramfs archive is a gzipped cpio archive (like tar only simpler,
+ see cpio(1) and Documentation/early-userspace/buffer-format.txt).
+
+ - The program run by the old initrd (which was called /initrd, not /init) did
+ some setup and then returned to the kernel, while the init program from
+ initramfs is not expected to return to the kernel. (If /init needs to hand
+ off control it can overmount / with a new root device and exec another init
+ program. See the switch_root utility, below.)
+
+ - When switching another root device, initrd would pivot_root and then
+ umount the ramdisk. But initramfs is rootfs: you can neither pivot_root
+ rootfs, nor unmount it. Instead delete everything out of rootfs to
+ free up the space (find -xdev / -exec rm '{}' ';'), overmount rootfs
+ with the new root (cd /newmount; mount --move . /; chroot .), attach
+ stdin/stdout/stderr to the new /dev/console, and exec the new init.
+
+ Since this is a remarkably persnickity process (and involves deleting
+ commands before you can run them), the klibc package introduced a helper
+ program (utils/run_init.c) to do all this for you. Most other packages
+ (such as busybox) have named this command "switch_root".
+
+Populating initramfs:
+---------------------
+
+The 2.6 kernel build process always creates a gzipped cpio format initramfs
+archive and links it into the resulting kernel binary. By default, this
+archive is empty (consuming 134 bytes on x86). The config option
+CONFIG_INITRAMFS_SOURCE (for some reason buried under devices->block devices
+in menuconfig, and living in usr/Kconfig) can be used to specify a source for
+the initramfs archive, which will automatically be incorporated into the
+resulting binary. This option can point to an existing gzipped cpio archive, a
+directory containing files to be archived, or a text file specification such
+as the following example:
+
+ dir /dev 755 0 0
+ nod /dev/console 644 0 0 c 5 1
+ nod /dev/loop0 644 0 0 b 7 0
+ dir /bin 755 1000 1000
+ slink /bin/sh busybox 777 0 0
+ file /bin/busybox initramfs/busybox 755 0 0
+ dir /proc 755 0 0
+ dir /sys 755 0 0
+ dir /mnt 755 0 0
+ file /init initramfs/init.sh 755 0 0
+
+One advantage of the text file is that root access is not required to
+set permissions or create device nodes in the new archive. (Note that those
+two example "file" entries expect to find files named "init.sh" and "busybox" in
+a directory called "initramfs", under the linux-2.6.* directory. See
+Documentation/early-userspace/README for more details.)
+
+If you don't already understand what shared libraries, devices, and paths
+you need to get a minimal root filesystem up and running, here are some
+references:
+http://www.tldp.org/HOWTO/Bootdisk-HOWTO/
+http://www.tldp.org/HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.html
+http://www.linuxfromscratch.org/lfs/view/stable/
+
+The "klibc" package (http://www.kernel.org/pub/linux/libs/klibc) is
+designed to be a tiny C library to statically link early userspace
+code against, along with some related utilities. It is BSD licensed.
+
+I use uClibc (http://www.uclibc.org) and busybox (http://www.busybox.net)
+myself. These are LGPL and GPL, respectively.
+
+In theory you could use glibc, but that's not well suited for small embedded
+uses like this. (A "hello world" program statically linked against glibc is
+over 400k. With uClibc it's 7k. Also note that glibc dlopens libnss to do
+name lookups, even when otherwise statically linked.)
+
+Future directions:
+------------------
+
+Today (2.6.14), initramfs is always compiled in, but not always used. The
+kernel falls back to legacy boot code that is reached only if initramfs does
+not contain an /init program. The fallback is legacy code, there to ensure a
+smooth transition and allowing early boot functionality to gradually move to
+"early userspace" (I.E. initramfs).
+
+The move to early userspace is necessary because finding and mounting the real
+root device is complex. Root partitions can span multiple devices (raid or
+separate journal). They can be out on the network (requiring dhcp, setting a
+specific mac address, logging into a server, etc). They can live on removable
+media, with dynamically allocated major/minor numbers and persistent naming
+issues requiring a full udev implementation to sort out. They can be
+compressed, encrypted, copy-on-write, loopback mounted, strangely partitioned,
+and so on.
+
+This kind of complexity (which inevitably includes policy) is rightly handled
+in userspace. Both klibc and busybox/uClibc are working on simple initramfs
+packages to drop into a kernel build, and when standard solutions are ready
+and widely deployed, the kernel's legacy early boot code will become obsolete
+and a candidate for the feature removal schedule.
+
+But that's a while off yet.

+is the software layer in the kernel that provides the filesystem

+within the kernel which allows different filesystem implementations to
+coexist.
+VFS system calls open(2), stat(2), read(2), write(2), chmod(2) and so

+in the document Documentation/filesystems/Locking.
-A Quick Look At How It Works
-============================
-In this section I'll briefly describe how things work, before
-launching into the details. I'll start with describing what happens
-when user programs open and manipulate files, and then look from the
-other view which is how a filesystem is supported and subsequently
-mounted.
-
-
-Opening a File
---------------
-
-The VFS implements the open(2), stat(2), chmod(2) and similar system
-calls. The pathname argument is used by the VFS to search through the
-directory entry cache (dentry cache or "dcache"). This provides a very
-fast look-up mechanism to translate a pathname (filename) into a
-specific dentry.
-
-An individual dentry usually has a pointer to an inode. Inodes are the
-things that live on disc drives, and can be regular files (you know:
-those things that you write data into), directories, FIFOs and other
-beasts. Dentries live in RAM and are never saved to disc: they exist
-only for performance. Inodes live on disc and are copied into memory
-when required. Later any changes are written back to disc. The inode
-that lives in RAM is a VFS inode, and it is this which the dentry
-points to. A single inode can be pointed to by multiple dentries
-(think about hardlinks).
-
-The dcache is meant to be a view into your entire filespace. Unlike
-Linus, most of us losers can't fit enough dentries into RAM to cover
-all of our filespace, so the dcache has bits missing. In order to
-resolve your pathname into a dentry, the VFS may have to resort to
-creating dentries along the way, and then loading the inode. This is
-done by looking up the inode.
-
-To look up an inode (usually read from disc) requires that the VFS
-calls the lookup() method of the parent directory inode. This method
-is installed by the specific filesystem implementation that the inode
-lives in. There will be more on this later.
+Directory Entry Cache (dcache)
+------------------------------
-Once the VFS has the required dentry (and hence the inode), we can do
-all those boring things like open(2) the file, or stat(2) it to peek
-at the inode data. The stat(2) operation is fairly simple: once the
-VFS has the dentry, it peeks at the inode data and passes some of it
-back to userspace.
+The VFS implements the open(2), stat(2), chmod(2), and similar system
+calls. The pathname argument that is passed to them is used by the VFS
+to search through the directory entry cache (also known as the dentry
+cache or dcache). This provides a very fast look-up mechanism to
+translate a pathname (filename) into a specific dentry. Dentries live
+in RAM and are never saved to disc: they exist only for performance.
+
+The dentry cache is meant to be a view into your entire filespace. As
+most computers cannot fit all dentries in the RAM at the same time,
+some bits of the cache are missing. In order to resolve your pathname
+into a dentry, the VFS may have to resort to creating dentries along
+the way, and then loading the inode. This is done by looking up the
+inode.
+
+
+The Inode Object
+----------------
+
+An individual dentry usually has a pointer to an inode. Inodes are
+filesystem objects such as regular files, directories, FIFOs and other
+beasts. They live either on the disc (for block device filesystems)
+or in the memory (for pseudo filesystems). Inodes that live on the
+disc are copied into the memory when required and changes to the inode
+are written back to disc. A single inode can be pointed to by multiple
+dentries (hard links, for example, do this).
+
+To look up an inode requires that the VFS calls the lookup() method of
+the parent directory inode. This method is installed by the specific
+filesystem implementation that the inode lives in. Once the VFS has
+the required dentry (and hence the inode), we can do all those boring
+things like open(2) the file, or stat(2) it to peek at the inode
+data. The stat(2) operation is fairly simple: once the VFS has the
+dentry, it peeks at the inode data and passes some of it back to
+userspace.
+
+
+The File Object
+---------------
Opening a file requires another operation: allocation of a file
structure (this is the kernel-side implementation of file
a pointer to the dentry and a set of file operation member functions.
These are taken from the inode data. The open() file method is then
called so the specific filesystem implementation can do it's work. You
-can see that this is another switch performed by the VFS.
-
-The file structure is placed into the file descriptor table for the
-process.
+can see that this is another switch performed by the VFS. The file
+structure is placed into the file descriptor table for the process.
Reading, writing and closing files (and other assorted VFS operations)
is done by using the userspace file descriptor to grab the appropriate
-file structure, and then calling the required file structure method
-function to do whatever is required.
-
-For as long as the file is open, it keeps the dentry "open" (in use),
-which in turn means that the VFS inode is still in use.
-
-All VFS system calls (i.e. open(2), stat(2), read(2), write(2),
-chmod(2) and so on) are called from a process context. You should
-assume that these calls are made without any kernel locks being
-held. This means that the processes may be executing the same piece of
-filesystem or driver code at the same time, on different
-processors. You should ensure that access to shared resources is
-protected by appropriate locks.

Registering and Mounting a Filesystem
--------------------------------------
+=====================================
-If you want to support a new kind of filesystem in the kernel, all you
-need to do is call register_filesystem(). You pass a structure
-describing the filesystem implementation (struct file_system_type)
-which is then added to an internal table of supported filesystems. You
-can do:
+To register and unregister a filesystem, use the following API
+functions:
-% cat /proc/filesystems
+ #include <linux/fs.h>
-to see what filesystems are currently available on your system.
+ extern int register_filesystem(struct file_system_type *);
+ extern int unregister_filesystem(struct file_system_type *);
-When a request is made to mount a block device onto a directory in
-your filespace the VFS will call the appropriate method for the
-specific filesystem. The dentry for the mount point will then be
-updated to point to the root inode for the new filesystem.
+The passed struct file_system_type describes your filesystem. When a
+request is made to mount a device onto a directory in your filespace,
+the VFS will call the appropriate get_sb() method for the specific
+filesystem. The dentry for the mount point will then be updated to
+point to the root inode for the new filesystem.
-It's now time to look at things in more detail.
+You can see all filesystems that are registered to the kernel in the
+file /proc/filesystems.

+For further information on dentry locking, please refer to the document
+Documentation/filesystems/dentry-locking.txt.
-RCU-based dcache locking model
-------------------------------
-On many workloads, the most common operation on dcache is
-to look up a dentry, given a parent dentry and the name
-of the child. Typically, for every open(), stat() etc.,
-the dentry corresponding to the pathname will be looked
-up by walking the tree starting with the first component
-of the pathname and using that dentry along with the next
-component to look up the next level and so on. Since it
-is a frequent operation for workloads like multiuser
-environments and web servers, it is important to optimize
-this path.
-
-Prior to 2.5.10, dcache_lock was acquired in d_lookup and thus
-in every component during path look-up. Since 2.5.10 onwards,
-fast-walk algorithm changed this by holding the dcache_lock
-at the beginning and walking as many cached path component
-dentries as possible. This significantly decreases the number
-of acquisition of dcache_lock. However it also increases the
-lock hold time significantly and affects performance in large
-SMP machines. Since 2.5.62 kernel, dcache has been using
-a new locking model that uses RCU to make dcache look-up
-lock-free.
-
-The current dcache locking model is not very different from the existing
-dcache locking model. Prior to 2.5.62 kernel, dcache_lock
-protected the hash chain, d_child, d_alias, d_lru lists as well
-as d_inode and several other things like mount look-up. RCU-based
-changes affect only the way the hash chain is protected. For everything
-else the dcache_lock must be taken for both traversing as well as
-updating. The hash chain updates too take the dcache_lock.
-The significant change is the way d_lookup traverses the hash chain,
-it doesn't acquire the dcache_lock for this and rely on RCU to
-ensure that the dentry has not been *freed*.

-For many multi-user workloads, open() and stat() on files are
-very frequently occurring operations. Both involve walking
-of path names to find the dentry corresponding to the
-concerned file. In 2.4 kernel, dcache_lock was held
-during look-up of each path component. Contention and
-cache-line bouncing of this global lock caused significant
-scalability problems. With the introduction of RCU
-in Linux kernel, this was worked around by making
-the look-up of path components during path walking lock-free.
-
-
-Safe lock-free look-up of dcache hash table
-===========================================
-
-Dcache is a complex data structure with the hash table entries
-also linked together in other lists. In 2.4 kernel, dcache_lock
-protected all the lists. We applied RCU only on hash chain
-walking. The rest of the lists are still protected by dcache_lock.
-Some of the important changes are :
-
-1. The deletion from hash chain is done using hlist_del_rcu() macro which
- doesn't initialize next pointer of the deleted dentry and this
- allows us to walk safely lock-free while a deletion is happening.
-
-2. Insertion of a dentry into the hash table is done using
- hlist_add_head_rcu() which take care of ordering the writes -
- the writes to the dentry must be visible before the dentry
- is inserted. This works in conjunction with hlist_for_each_rcu()
- while walking the hash chain. The only requirement is that
- all initialization to the dentry must be done before hlist_add_head_rcu()
- since we don't have dcache_lock protection while traversing
- the hash chain. This isn't different from the existing code.
-
-3. The dentry looked up without holding dcache_lock by cannot be
- returned for walking if it is unhashed. It then may have a NULL
- d_inode or other bogosity since RCU doesn't protect the other
- fields in the dentry. We therefore use a flag DCACHE_UNHASHED to
- indicate unhashed dentries and use this in conjunction with a
- per-dentry lock (d_lock). Once looked up without the dcache_lock,
- we acquire the per-dentry lock (d_lock) and check if the
- dentry is unhashed. If so, the look-up is failed. If not, the
- reference count of the dentry is increased and the dentry is returned.
-
-4. Once a dentry is looked up, it must be ensured during the path
- walk for that component it doesn't go away. In pre-2.5.10 code,
- this was done holding a reference to the dentry. dcache_rcu does
- the same. In some sense, dcache_rcu path walking looks like
- the pre-2.5.10 version.
-
-5. All dentry hash chain updates must take the dcache_lock as well as
- the per-dentry lock in that order. dput() does this to ensure
- that a dentry that has just been looked up in another CPU
- doesn't get deleted before dget() can be done on it.
-
-6. There are several ways to do reference counting of RCU protected
- objects. One such example is in ipv4 route cache where
- deferred freeing (using call_rcu()) is done as soon as
- the reference count goes to zero. This cannot be done in
- the case of dentries because tearing down of dentries
- require blocking (dentry_iput()) which isn't supported from
- RCU callbacks. Instead, tearing down of dentries happen
- synchronously in dput(), but actual freeing happens later
- when RCU grace period is over. This allows safe lock-free
- walking of the hash chains, but a matched dentry may have
- been partially torn down. The checking of DCACHE_UNHASHED
- flag with d_lock held detects such dentries and prevents
- them from being returned from look-up.
-
-
-Maintaining POSIX rename semantics
-==================================
-
-Since look-up of dentries is lock-free, it can race against
-a concurrent rename operation. For example, during rename
-of file A to B, look-up of either A or B must succeed.
-So, if look-up of B happens after A has been removed from the
-hash chain but not added to the new hash chain, it may fail.
-Also, a comparison while the name is being written concurrently
-by a rename may result in false positive matches violating
-rename semantics. Issues related to race with rename are
-handled as described below :
-
-1. Look-up can be done in two ways - d_lookup() which is safe
- from simultaneous renames and __d_lookup() which is not.
- If __d_lookup() fails, it must be followed up by a d_lookup()
- to correctly determine whether a dentry is in the hash table
- or not. d_lookup() protects look-ups using a sequence
- lock (rename_lock).
-
-2. The name associated with a dentry (d_name) may be changed if
- a rename is allowed to happen simultaneously. To avoid memcmp()
- in __d_lookup() go out of bounds due to a rename and false
- positive comparison, the name comparison is done while holding the
- per-dentry lock. This prevents concurrent renames during this
- operation.
-
-3. Hash table walking during look-up may move to a different bucket as
- the current dentry is moved to a different bucket due to rename.
- But we use hlists in dcache hash table and they are null-terminated.
- So, even if a dentry moves to a different bucket, hash chain
- walk will terminate. [with a list_head list, it may not since
- termination is when the list_head in the original bucket is reached].
- Since we redo the d_parent check and compare name while holding
- d_lock, lock-free look-up will not race against d_move().
-
-4. There can be a theoretical race when a dentry keeps coming back
- to original bucket due to double moves. Due to this look-up may
- consider that it has never moved and can end up in a infinite loop.
- But this is not any worse that theoretical livelocks we already
- have in the kernel.
-
-
-Important guidelines for filesystem developers related to dcache_rcu
-====================================================================
-
-1. Existing dcache interfaces (pre-2.5.62) exported to filesystem
- don't change. Only dcache internal implementation changes. However
- filesystems *must not* delete from the dentry hash chains directly
- using the list macros like allowed earlier. They must use dcache
- APIs like d_drop() or __d_drop() depending on the situation.
-
-2. d_flags is now protected by a per-dentry lock (d_lock). All
- access to d_flags must be protected by it.
-
-3. For a hashed dentry, checking of d_count needs to be protected
- by d_lock.

I've seen reports that bttv 0.7.x crashes whereas 0.8.x works rock solid
for some people. Thus probably a small buglet left somewhere in bttv
Users can use the huge page support in Linux kernel by either using the mmap
system call or standard SYSv shared memory system calls (shmget, shmat).
-First the Linux kernel needs to be built with CONFIG_HUGETLB_PAGE (present
-under Processor types and feature) and CONFIG_HUGETLBFS (present under file
-system option on config menu) config options.

The kernel built with hugepage support should show the number of configured

inodes that /mnt/huge can use. If the size or nr_inode options are not
provided on command line then no limits are set. For size and nr_inodes

*
* There are 5 different IPL methods
* 1) load the image directly into ram at address 0 and do an PSW restart
* 5) direct call of start by the SALIPL loader
* We use the cpuid to distinguish between VM and native ipl
* params for kernel are pushed to 0x10400 (see setup.h)
-
- Changes:
- Okt 25 2000 <rvdheij@iae.nl>
- added code to skip HDR and EOF to allow SL tape IPL (5 retries)
- changed first CCW from rewind to backspace block

*
- * There are 5 different IPL methods
- * 1) load the image directly into ram at address 0 and do an PSW restart
- * 2) linload will load the image from address 0x10000 to memory 0x10000
- * and start the code thru LPSW 0x0008000080010000 (VM only, deprecated)
- * 3) generate the tape ipl header, store the generated image on a tape
- * and ipl from it
- * In case of SL tape you need to IPL 5 times to get past VOL1 etc
- * 4) generate the vm reader ipl header, move the generated image to the
- * VM reader (use option NOH!) and do a ipl from reader (VM only)
- * 5) direct call of start by the SALIPL loader
- * We use the cpuid to distinguish between VM and native ipl
- * params for kernel are pushed to 0x10400 (see setup.h)
-
- Changes:
- Okt 25 2000 <rvdheij@iae.nl>
- added code to skip HDR and EOF to allow SL tape IPL (5 retries)
- changed first CCW from rewind to backspace block

/* DOC_PASSIVE_PROBE:
- In order to ensure that the BIOS checksum is correct at boot time, and
- hence that the onboard BIOS extension gets executed, the DiskOnChip
- goes into reset mode when it is read sequentially: all registers
- return 0xff until the chip is woken up again by writing to the
- DOCControl register.
-
- Unfortunately, this means that the probe for the DiskOnChip is unsafe,
- because one of the first things it does is write to where it thinks
- the DOCControl register should be - which may well be shared memory

+ - support asynchronous operation -- add a per-fs 'reserved_space' count,
+ let each outstanding write reserve the _maximum_ amount of physical
+ space it could take. Let GC flush the outstanding writes because the
+ reservations will necessarily be pessimistic. With this we could even
+ do shared writable mmap, if we can have a fs hook for do_wp_page() to
+ make the reservation.
- disable compression in commit_write()?
- fine-tune the allocation / GC thresholds
- chattr support - turning on/off and tuning compression per-inode
- test, test, test
- NAND flash support:
- - flush_wbuf using GC to fill it, don't just pad.
- - Deal with write errors. Data don't get lost - we just have to write
- the affected node(s) out again somewhere else.
- - make fsync flush only if actually required
- - make sys_sync() work.
- - reboot notifier
- - timed flush of old wbuf
- - fix magical second arg of jffs2_flush_wbuf(). Split into two or more functions instead.
-
+ - almost done :)
+ - use bad block check instead of the hardwired byte check
- Optimisations:
- - Stop GC from decompressing and immediately recompressing nodes which could
- just be copied intact. (We now keep track of REF_PRISTINE flag. Easy now.)
- - Furthermore, in the case where it could be copied intact we don't even need
- to call iget() for it -- if we use (raw_node_raw->flash_offset & 2) as a flag
- to show a node can be copied intact and it's _not_ in icache, we could just do
- it, fix up the next_in_ino list and move on. We would need a way to find out
- _whether_ it's in icache though -- if it's in icache we also need to do the
- fragment lists, etc. P'raps a flag or pointer in the jffs2_inode_cache could
- help. (We have half of this now.)
+ - Split writes so they go to two separate blocks rather than just c->nextblock.
+ By writing _new_ nodes to one block, and garbage-collected REF_PRISTINE
+ nodes to a different one, we can separate clean nodes from those which
+ are likely to become dirty, and end up with blocks which are each far
+ closer to 100% or 0% clean, hence speeding up later GC progress dramatically.
- Stop keeping name in-core with struct jffs2_full_dirent. If we keep the hash in
the full dirent, we only need to go to the flash in lookup() when we think we've
got a match, and in readdir().
- Remove totlen from jffs2_raw_node_ref? Need to have totlen passed into
jffs2_mark_node_obsolete(). Can all callers work it out?
- Remove size from jffs2_raw_node_frag.
+
+dedekind:
+1. __jffs2_flush_wbuf() has a strange 'pad' parameter. Eliminate.
+2. get_sb()->build_fs()->scan() path... Why get_sb() removes scan()'s crap in
+ case of failure? scan() does not clean everything. Fix.

+/* Random Early Detection (RED) algorithm.
+ =======================================
+
+ Source: Sally Floyd and Van Jacobson, "Random Early Detection Gateways
+ for Congestion Avoidance", 1993, IEEE/ACM Transactions on Networking.
+
+ This file codes a "divisionless" version of RED algorithm
+ as written down in Fig.17 of the paper.
+
+ Short description.
+ ------------------
+
+ When a new packet arrives we calculate the average queue length:
+
+ avg = (1-W)*avg + W*current_queue_len,
+
+ W is the filter time constant (chosen as 2^(-Wlog)), it controls
+ the inertia of the algorithm. To allow larger bursts, W should be
+ decreased.
+
+ if (avg > th_max) -> packet marked (dropped).
+ if (avg < th_min) -> packet passes.
+ if (th_min < avg < th_max) we calculate probability:
+
+ Pb = max_P * (avg - th_min)/(th_max-th_min)
+
+ and mark (drop) packet with this probability.
+ Pb changes from 0 (at avg==th_min) to max_P (avg==th_max).
+ max_P should be small (not 1), usually 0.01..0.02 is good value.
+
+ max_P is chosen as a number, so that max_P/(th_max-th_min)
+ is a negative power of two in order arithmetics to contain
+ only shifts.
+
+
+ Parameters, settable by user:
+ -----------------------------
+
+ qth_min - bytes (should be < qth_max/2)
+ qth_max - bytes (should be at least 2*qth_min and less limit)
+ Wlog - bits (<32) log(1/W).

* Description:
- *
+ *
* The generic Reed Solomon library provides runtime configurable
* encoding / decoding of RS codes.
* Each user must call init_rs to get a pointer to a rs_control
* If a structure is generated then the polynomial arrays for
* fast encoding / decoding are built. This can take some time so
* make sure not to call this function from a time critical path.
- * Usually a module / driver should initialize the necessary
+ * Usually a module / driver should initialize the necessary
* rs_control structure on module / driver init and release it
* on exit.
- * The encoding puts the calculated syndrome into a given syndrome
- * buffer.
+ * The encoding puts the calculated syndrome into a given syndrome
+ * buffer.
* The decoding is a two step process. The first step calculates
* the syndrome over the received (data + syndrome) and calls the
* second stage, which does the decoding / error correction itself.

-/* Random Early Detection (RED) algorithm.
- =======================================
-
- Source: Sally Floyd and Van Jacobson, "Random Early Detection Gateways
- for Congestion Avoidance", 1993, IEEE/ACM Transactions on Networking.
-
- This file codes a "divisionless" version of RED algorithm
- as written down in Fig.17 of the paper.
-
-Short description.
-------------------
-
- When a new packet arrives we calculate the average queue length:
-
- avg = (1-W)*avg + W*current_queue_len,
-
- W is the filter time constant (chosen as 2^(-Wlog)), it controls
- the inertia of the algorithm. To allow larger bursts, W should be
- decreased.
-
- if (avg > th_max) -> packet marked (dropped).
- if (avg < th_min) -> packet passes.
- if (th_min < avg < th_max) we calculate probability:
-
- Pb = max_P * (avg - th_min)/(th_max-th_min)
-
- and mark (drop) packet with this probability.
- Pb changes from 0 (at avg==th_min) to max_P (avg==th_max).
- max_P should be small (not 1), usually 0.01..0.02 is good value.
-
- max_P is chosen as a number, so that max_P/(th_max-th_min)
- is a negative power of two in order arithmetics to contain
- only shifts.
-
-
- Parameters, settable by user:
+/* Parameters, settable by user:
-----------------------------
limit - bytes (must be > qth_max + burst)
arbitrarily high (well, less than ram size)
Really, this limit will never be reached
if RED works correctly.
-
- qth_min - bytes (should be < qth_max/2)
- qth_max - bytes (should be at least 2*qth_min and less limit)
- Wlog - bits (<32) log(1/W).
- Plog - bits (<32)
-
- Plog is related to max_P by formula:
-
- max_P = (qth_max-qth_min)/2^Plog;
-
- F.e. if qth_max=128K and qth_min=32K, then Plog=22
- corresponds to max_P=0.02
-
- Scell_log
- Stab
-
- Lookup table for log((1-W)^(t/t_ave).
-
-
-NOTES:
-
-Upper bound on W.
------------------
-
- If you want to allow bursts of L packets of size S,
- you should choose W:
-
- L + 1 - th_min/S < (1-(1-W)^L)/W
-
- th_min/S = 32 th_min/S = 4
-
- log(W) L
- -1 33
- -2 35
- -3 39
- -4 46
- -5 57
- -6 75
- -7 101
- -8 135
- -9 190
- etc.

* azt3328.c - driver for Aztech AZF3328 based soundcards (e.g. PCI168).
- * Copyright (C) 2002 by Andreas Mohr <hw7oshyuv3001@sneakemail.com>
+ * Copyright (C) 2002, 2005 by Andreas Mohr <andi AT lisas.de>
*
* Framework borrowed from Bart Hartgers's als4000.c.
* Driver developed on PCI168 AP(W) version (PCI rev. 10, subsystem ID 1801),
* - MPU401 (+ legacy address support) FIXME: how to enable legacy addr??
* - game port (legacy address support)
* - built-in General DirectX timer having a 20 bits counter
- * with 1us resolution (FIXME: where is it?)
+ * with 1us resolution (see below!)
* - I2S serial port for external DAC
* - supports 33MHz PCI spec 2.1, PCI power management 1.0, compliant with ACPI
* - supports hardware volume control
* required for Microsoft's logo compliance (FIXME: where?)
* - PCI168 AP(W) card: power amplifier with 4 Watts/channel at 4 Ohms
*
+ * Note that this driver now is actually *better* than the Windows driver,
+ * since it additionally supports the card's 1MHz DirectX timer - just try
+ * the following snd-seq module parameters etc.:
+ * - options snd-seq seq_default_timer_class=2 seq_default_timer_sclass=0
+ * seq_default_timer_card=0 seq_client_load=1 seq_default_timer_device=0
+ * seq_default_timer_subdevice=0 seq_default_timer_resolution=1000000
+ * - "timidity -iAv -B2,8 -Os -EFreverb=0"
+ * - "pmidi -p 128:0 jazz.mid"
+ *
* Certain PCI versions of this card are susceptible to DMA traffic underruns
* in some systems (resulting in sound crackling/clicking/popping),
* probably because they don't have a DMA FIFO buffer or so.
* Overview (PCI ID/PCI subID/PCI rev.):
* - no DMA crackling on SiS735: 0x50DC/0x1801/16
* - unknown performance: 0x50DC/0x1801/10
- *
+ * (well, it's not bad on an Athlon 1800 with now very optimized IRQ handler)
+ *
* Crackling happens with VIA chipsets or, in my case, an SiS735, which is
* supposed to be very fast and supposed to get rid of crackling much
* better than a VIA, yet ironically I still get crackling, like many other
* - Disable ACPI/power management/"Auto Detect RAM/PCI Clk" in BIOS
*
* BUGS
- * - when Ctrl-C'ing mpg321, the playback loops a bit
- * (premature DMA playback reset?)
- * - full-duplex sometimes breaks (IRQ management issues?).
- * Once even a spontaneous REBOOT happened!!!
+ * - full-duplex might *still* be problematic, not fully tested recently
*
* TODO
* - test MPU401 MIDI playback etc.
- * - power management (CONFIG_PM). See e.g. intel8x0 or cs4281.
+ * - power management. See e.g. intel8x0 or cs4281.
* This would be nice since the chip runs a bit hot, and it's *required*
- * anyway for proper ACPI power management. In other words: rest
- * assured that I *will* implement this very soon; as soon as Linux 2.5.x
- * has power management that's bugfree enough to work properly on my desktop.
+ * anyway for proper ACPI power management.
* - figure out what all unknown port bits are responsible for
