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.
