[GIT PULL] Btrfs

[Chris Mason]

Hi Linus,

We have another round of fixes and a few cleanups in my for-linus-4.7
branch:

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

I have a fix for short returns from btrfs_copy_from_user, which finally
nails down a very hard to find regression we added in v4.6.

Dave is pushing around gfp parameters, mostly to cleanup internal apis
and make it a little more consistent.  The rest are smaller fixes, and
one speelling fixup patch.
