[GIT PULL] Btrfs

[Chris Mason]

Hi Linus,

This is part two of my btrfs pull, which is some cleanups and a batch of
fixes.  

Most of the code here is from Jeff Mahoney, making the pointers
we pass around internally more consistent and less confusing overall.  I
noticed a small problem right before I sent this out yesterday, so I
fixed it up and re-tested overnight.

Please pull my for-linus-4.8 branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.8

There are some minor conflicts against Mike Christie's changes in
your tree.  I've put the conflict resolution I used for testing here:
