[GIT PULL] Btrfs

[Chris Mason]

Hi Linus

My for-linus-4.7 branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.7

Has some fixes and some new self tests for btrfs.  The self tests are
usually disabled in the .config file (unless you're doing btrfs dev
work), and this bunch is meant to find problems with the 64K page
size patches.

Jeff has a patch to help people see if they are using the hardware
assist crc32c module, which really helps us nail down problems when
people ask why crcs are using so much CPU.

Otherwise, it's small fixes.
