I don't know about a "long way" (longer to fully supported, yes)
Firstly, I need to move its hooks out of linux-2.6/xfs_iops.c which were 
referring to xfs inodes (instead of vnodes) probably back where they were in
xfs_vnodeops.c.

Nathan, did you have some other suggestion than this - unfortunately,
I haven't looked at this code (until recently) for a while.

Cheers,
Tim.
