[PULL] Btrfs updates for 4.10

[David Sterba <dsterba@suse.com>]

Hi,

here's my first pull request for 4.10. Assorted patches that have been in
for-next, mostly fixes and some cleanups. I'm expecting to send one more before
the rc1, I don't see much reason to hold the current queue back for any longer.
