Judging by the extended debug info in:
http://nerdbynature.de/bits/2.6.39-rc4/oom/ (The -9 files are the current ones)
that thing shows a _lot_ of xfs inodes:
xfs_inode 479187 479187 1120 14 4 : tunables 0 0 0 : slabdata 34329 34329 0
even though there aren't that many dentries (each inode should have at least one dentry associated with it under normal circumstances):
dentry 97896 97900 160 25 1 : tunables 0 0 0 : slabdata 3916 3916 0
and then later when the system gets low on memory, the dentries shrink:
dentry 1017 3525 160 25 1 : tunables 0 0 0 : slabdata 141 141 0
but the XFS inodes do not:
xfs_inode 557579 557579 1120 14 4 : tunables 0 0 0 : slabdata 41492 41492 0
so I suspect it's some kind of XFS inode leak.
