[PULL] Btrfs fixes for 4.9-rc4

[David Sterba <dsterba@suse.com>]

Hi,

please pull the following assorted small fixes to 4.9, thanks. The branch is
"rc3" as it was meant for rc3 but I did not get to sending the pull request,
and I don't want to recreate the branch just because of a slightly wrong
name.
