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.
