Hi Linus,

The following patches address shrinker lockdep and performance
regressions introduced into XFS in 2.6.34 when a shrinker was
added at the last moment to address OOM issues with lazy XFS inode
reclaim.

The first two patches are the saem as I originally posted to solve
the problem for 2.6.34. They did not pass review in time for 2.6.34,
and attempts to address said review comments resulted in a bigger,
more contentious patchset that has much bigger issues than this
patchset. Time has run out and I really don't want to have another
kernel released with XFS causing lockdep to trigger the moment
memory reclaim starts, so I'm asking if you will accept the original
fixes I posted for the problem.

The third patch addresses shrinker inode scanning performance
problems raised in recently here:

https://bugzilla.kernel.org/show_bug.cgi?id=16348

Please consider these commits for 2.6.26-rc6.

Cheers,

Dave.
