Merge branch 'for-linus' of git://git.kernel.dk/linux-block

Pull block fixes from Jens Axboe:
 "A set of fixes that wasn't included in the first merge window pull
  request.  This pull request contains:

   - A set of NVMe fixes from Keith, and one from Nic for the integrity
     side of it.

   - Fix from Ming, clearing ->mq_ops if we don't successfully setup a
     queue for multiqueue.

   - A set of stability fixes for bcache from Jiri, and also marking
     bcache as orphaned as it's no longer actively maintained (in
     mainline, at least)"
