For some reason this never got any traction.  Below is a respin against
curently mainline.  The preallocations are still released later so no
progress on that end.  Because this is the last instance of ->put_inode
I'd like to move forward on getting rid of it.

Is there any chance you could either send me a affs image to run fsx
on it or do it yourself?
