I'll ask my boss about it. Unfortunately we found opposite issue with
memory management + XFS (100M of inodes) on 2.6.38: some objects in
xfs_inode and dentry slabs are seems to be never cleared (at least
without "sync && echo 2 >.../drop_caches"). But this is not a
production machine working 24x7, so we don't care about it right now.
