[SCSI] Fix async scanning double-add problems
Stress-testing and some thought has revealed some places where
asynchronous scanning needs some more attention to locking.
- Since async_scan is a bit, we need to hold the host_lock while
modifying it to prevent races against other CPUs modifying the word
that bit is in. This is probably a theoretical race for the moment,
but other patches may change that.
- The async_scan bit means not only that this host is being scanned
asynchronously, but that all the devices attached to this host are not
yet added to sysfs. So we must ensure that this bit is always in sync.
I've chosen to do this with the scan_mutex since it's already acquired
in most of the right places.
- If the host changes state to deleted while we're in the middle of
a scan, we'll end up with some devices on the host's list which must
be deleted. Add a check to scsi_sysfs_add_devices() to ensure the
host is still running.
- To avoid the async_scan bit being protected by three locks, the
async_scan_lock now only protects the scanning_list.

don't work like that.
This adds I_T nexus support, which enable one scsi_host to handle
multiple initiators. New scsi_tgt_it_nexus_create/destroy functions
are expected be called transport classes. For example, ibmvstgt
creates an initiator remote port, then the srp transport calls
tgt_it_nexus_create. tgt doesn't manages I_T nexus, instead it tells
tgtd, user-space daemon, to create a new I_T nexus.
On the receiving the response from tgtd, tgt calls
shost->transportt->it_nexus_response. transports should notify a

[GFS2] soft lockup in rgblk_search
This patch seems to fix the problem described in bugzilla bug 246114.
It was written by Steve Whitehouse with some tweaking by me.
The code was looping in the relatively new section of code designed to
search for and reuse unlinked inodes. In cases where it was finding an
appropriate inode to reuse, it was looping around and finding the same
block over and over because a "<=" check should have been a "<" when
comparing the goal block to the last unlinked block found.

[GFS2] soft lockup detected in databuf_lo_before_commit
This is part 2 of the patch for bug #245832, part 1 of which is already
in the git tree.
The problem was that sdp->sd_log_num_databuf was not always being
protected by the gfs2_log_lock spinlock, but the sd_log_le_databuf
(which it is supposed to reflect) was protected. That meant there
was a timing window during which gfs2_log_flush called
databuf_lo_before_commit and the count didn't match what was
really on the linked list in that window. So when it ran out of
items on the linked list, it decremented total_dbuf from 0 to -1 and
thus never left the "while(total_dbuf)" loop.
The solution is to protect the variable sdp->sd_log_num_databuf so
that the value will always match the contents of the linked list,
and therefore the number will never go negative, and therefore, the
loop will be exited properly.

[DLM] fix basts for granted PR waiting CW
Fix a long standing bug where a blocking callback would be missed
when there's a granted lock in PR mode and waiting locks in both
PR and CW modes (and the PR lock was added to the waiting queue
before the CW lock). The logic simply compared the numerical values
of the modes to determine if a blocking callback was required, but in
the one case of PR and CW, the lower valued CW mode blocks the higher
valued PR mode. We just need to add a special check for this PR/CW
case in the tests that decide when a blocking callback is needed.

[DLM] Fix memory leak in dlm_add_member() when dlm_node_weight() returns less than zero
There's a memory leak in fs/dlm/member.c::dlm_add_member().
If "dlm_node_weight(ls->ls_name, nodeid)" returns < 0, then
we'll return without freeing the memory allocated to the (at
that point yet unused) 'memb'.
This patch frees the allocated memory in that case and thus
avoids the leak.

[DLM] Clear othercon pointers when a connection is closed
This patch clears the othercon pointer and frees the memory when a connnection
is closed. This could cause a small memory leak when nodes leave the cluster.

[IPVS]: Use IP_VS_WAIT_WHILE when encessary.
For architectures that don't have a volatile atomic_ts constructs like
while (atomic_read(&something)); might result in endless loops since a
barrier() is missing which forces the compiler to generate code that
actually reads memory contents.
Fix this in ipvs by using the IP_VS_WAIT_WHILE macro which resolves to
while (expr) { cpu_relax(); }
(why isn't this open coded btw?)

[NET]: Share correct feature code between bridging and bonding
http://bugzilla.kernel.org/show_bug.cgi?id=8797 shows that the
bonding driver may produce bogus combinations of the checksum
flags and SG/TSO.
For example, if you bond devices with NETIF_F_HW_CSUM and
NETIF_F_IP_CSUM you'll end up with a bonding device that
has neither flag set. If both have TSO then this produces
an illegal combination.
The bridge device on the other hand has the correct code to
deal with this.
In fact, the same code can be used for both. So this patch
moves that logic into net/core/dev.c and uses it for both
bonding and bridging.
In the process I've made small adjustments such as only
setting GSO_ROBUST if at least one constituent device
supports it.
