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 our merge window series of cleanups and fixes. These target a wide
range of issues, but do include some important fixes for qgroups,
O_DIRECT, and fsync handling. Jeff Mahoney moved around a few
definitions to make them easier for userland to consume.

Also whiteout support is included now that issues with overlayfs have
been cleared up.

I have one more fix pending for page faults during btrfs_copy_from_user,
but I wanted to get this bulk out the door first.
