To tell the truth, I haven't even thought about how to fix it yet.
I suspect that the callbacks will need to be run, but with a new
parameter passed to xfs_iflush_done to say "still dirty, unlock
only" so that it simply unlocks and removes each object from the
buffer callback list.

I've got other things that need my attention right now (e.g agfl
size problem), so it's going to be next week before I get to this...

Cheers,

Dave.
