Subject: [GIT PULL] Fixes for 4.3 final

Hi Linus,

A final set of fixes for 4.3. It's (again) bigger than I would have
liked, but it's all been through the testing mill and has been carefully
reviewed by multiple parties. Each fix is either a regression fix for
this cycle, or is marked stable. You can scold me at KS.
The pull request contains:

- Three simple fixes for NVMe, fixing regressions since 4.3. From Arnd,
  Christoph, and Keith.

- A single xen-blkfront fix from Cathy, fixing a NULL dereference if an
  error is returned through the staste change callback.

- Fixup for some bad/sloppy code in nbd that got introduced earlier in
  this cycle. From Markus Pargmann.

- A blk-mq tagset use-after-free fix from Junichi.

- A backing device lifetime fix from Tejun, fixing a crash.

- And finally, a set of regression/stable fixes for cgroup writeback
  from Tejun.

Please pull!
