No worries about the noise. I was just trying to suggest something
that might be easier for you.
As near as I can tell XFS doesn't use the fs/quota functions at all,
yes? But if you add it into the fs/quota functions, it should get you
integration with ext2, ext3, ext4, jfs, ocfs2, and reiserfs. Yes?
