[PULL] Btrfs, misc for 4.6

[David Sterba <dsterba@suse.com>]

Hi,

a few low-risk patches that appeared after I sent my main pull for 4.6. I think
they still apply to 4.6, the freezer patches help the livepatch to clean up the
mis-use of the freezer API, the rest makes sure we don't miss an error during
writing checksums.

I've removed Liu Bo's patch fixing the writeback_index, IMO needs moe review
and can be merged in some later rc.
