Testing wise, the basic namespace operations work well (link, unlink, etc).
The rest has gotten less debugging (and I really don't have a great way of
testing the code in tree-log.c) Attached to this e-mail are btrfs-progs
patches which make testing of the changes possible.

Hi Mark,

I hit a few problems testing this, so I have the patch below that I plan
on folding into your commits (to keep bisect from crashing in tree log).

Just let me know if this is a problem, or if you see any bugs in there.
I'm still doing a last round of checks on it, but I wanted to send along
early for comments.

The biggest change in here is to always check the ref_objectid when
returning a backref.  Hash collisions mean we may return a ref for a
completely different parent id otherwise.  I think I caught all the
places missing that logic, but please double check me.

Ahh yes of course. I missed that in a couple key areas. Thanks for fixing
it.

Other than that I went through and fixed up bugs in
tree-log.c.  __add_inode_ref had a bunch of cut and paste errors, and you
carefully preserved a huge use-after-free bug in the original
add_inode_ref.

Cool, everything in there looks good to me. Thanks again Chris!
