[GIT PULL] Btrfs updates

[Chris Mason <chris.mason@fusionio.com>]

Hi Linus,

Please pull my for-linus branch:

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

The dates look like I had to rebase this morning because there was a compiler
warning for a printk arg that I had missed earlier.

These are all fixes, including one to prevent using stale pointers for
device names, and lots of fixes around transaction abort cleanups
(Josef, Liu Bo).

Jan Schmidt also sent in a number of fixes for the new reference number
tracking code.

Liu Bo beat me to updating the MAINTAINERS file.  Since he thought to
also fix the git url, I kept his commit.
