Merge branch 'for-linus-4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs updates from Chris Mason:
"This pull is dedicated to Josef's enospc rework, which we've been
testing for a few releases now. It fixes some early enospc problems
and is dramatically faster.
This also includes an updated fix for the delalloc accounting that
happens after a fault in copy_from_user. My patch in v4.7 was almost
but not quite enough"
