Rename actually_do_remove() to remove_files_and_dir(), make it call

ENOENT is probably due to multiple threads calling the exitcall functions
together*, but fixing that is non-trivial; and ignoring it is perfectly ok
in any case.

* it can surely happen: last_ditch_exit() is installed as SIGTERM handler
  at boot, and it's not removed on thread creation.  So killall vmlinux
  (which I do) surely causes that.  I've seen also a crash which seems to
  do the same.

Installing the handler on only the main thread would make UML do no cleanup
when another thread exits, and we're not sure we want that.  And mutual
exclusion in that context is tricky - we can't use spinlock in code not on

it returns 0 but forgets to remove it.  The fix is to remove it anytime
we're going to return 0.

But since "not_dead_yet" didn't make the interface so clear, causing this
bug, and I couldn't find a convenient name for the mix of things it did, I
split it into two parts:

is_umdir_used()      - returns a boolean, contains all checks of not_dead_yet()
umdir_take_if_dead   - tries to remove the dir unless it's used - returns
whether it removed it, that is we now own it.

With this changes the control flow is IMHO a bit clearer and needs less
comment for control flow.

[PATCH] uml: make copy_*_user atomic

Make __copy_*_user_inatomic really atomic to avoid "Sleeping function called in
atomic context" warnings, especially from futex code.

This is made by adding another kmap_atomic slot and making copy_*_user_skas
use kmap_atomic; also copy_*_user() becomes atomic, but that's true and is not
a problem for i386 (and we can always add might_sleep there as done
elsewhere).  For TT mode kmap is not used, so there's no need for this.

I've had to use another slot since both KM_USER0 and KM_USER1 are used
elsewhere and could cause conflicts.  Till now we reused the kmap_atomic slot
list from the subarch, but that's not needed as that list must contain the
common ones (used by generic code) + the ones used in architecture specific
code (and Uml till now used none); so I've taken the i386 one after comparing
it with ones from other archs, and added KM_UML_USERCOPY.

The problem was that I was updating the head register multiple times in the
rcvhdrq processing loop, and setting the counter on each update.  Since that
meant that the tail register was ahead of head for all but the last update, we
would get extra interrupts.  The fix was to not write the counter value except
on the last update.

I also changed to update rcvhdrhead and rcvegrindexhead at most every 16
packets, if there were lots of packets in the queue (and of course, on the
last packet, regardless).

I also made some small cleanups while debugging this.

With these changes, xeon/monty typically sees two openib packets per interrupt
on sdp and ipoib, opteron/monty is about 1.25 pkts/intr.

I'm seeing about 3800 Mbit/s monty/xeon, and 5000-5100 opteron/monty with
netperf sdp.  Netpipe doesn't show as good as that, peaking at about 4400 on
opteron/monty sdp.  Plain ipoib xeon is about 2100+ netperf, opteron 2900+, at

[PATCH] IB/ipath: enforce device resource limits

These limits are somewhat artificial in that we don't actually have any
device limits.  However, the verbs layer expects that such limits exist
and are enforced, so we make up arbitrary (but sensible) limits.

[PATCH] add rule filterkey

Add support for a rule key, which can be used to tie audit records to audit
rules.  This is useful when a watched file is accessed through a link or
symlink, as well as for general audit log analysis.

Because this patch uses a string key instead of an integer key, there is a bit
of extra overhead to do the kstrdup() when a rule fires.  However, we're also
allocating memory for the audit record buffer, so it's probably not that
significant.  I went ahead with a string key because it seems more
user-friendly.

Note that the user must ensure that filterkeys are unique.  The kernel only
checks for duplicate rules.
