Your best bet is to take the xfs cvs kernel, and apply the 2.4.22-pre
patch to it. Apart from kdb, it is usually pretty clean.

I don't think it's that easy. 2.4.22-pre has the O_DIRECT changes from sct. Fixing XFS so that it compiles isn't that difficult (just some conflicts in filemap.c) but it's much more work to not cripple XFS O_DIRECT support due to these new locks. Without any changes all O_DIRECT I/O would happen with i_sem held now.

Ya, unfortunately, its not that easy. I gave it a run, and there were a handful of failed hunks, _alot_ of fuzz & offsets. thanks though.
