Much better.

Btw, especially in inode land we should probably share even less code
with userspace.  Besides my old patches to kill the struct xfs_inode
abuse in repair phase 7 there isn't too much use of it left.

The db code uses inodes as temporary objects in the attrset code which
looks everything but efficient, and the mkfs and repair code use it to
create new files/directories.  Not quite sure bringing in all the kernel
code there makes so much sense given that we have other infrastructure
for a lot of these in userspace anyway.

I'm very happy to see this as I'd been aiming at it for a while.

Any chance you can add a script to pull in kernel changes automatically
while you're at it?
