[GIT PULL] Btrfs fixes

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

Hi Linus,

My for-linus branch:

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

Has our series of fixes for the next rc.  The biggest batch is from Jan
Schmidt, fixing up some problems in our subvolume quota code and fixing
btrfs send/receive to work with the new extended inode refs.

My git tree is against 3.6, but these were all retested against your
current git.
