[PULL] Btrfs for 4.8, part 1

[David Sterba <dsterba@suse.com>]

Hi,

please pull the following patches to 4.8. There are mostly small independent
fixes or cleanups. The branch is based on your current 'next' because of patch
dependencies. I don't want to start it on 4.7-rc6 as the merge conflicts would
be many and not trivial.

There are a few more patches that were sent but haven't received enough reviews
so I may send one more pull request should this change.
