[for-4.16 PATCH v4 0/4] block/dm: allow DM to defer blk_register_queue() until ready

[Mike Snitzer <snitzer@redhat.com>]

Hi Jens,

I think this set is now ready for you to pick up for 4.16.

Hannes, I ran with your review feedback and think the result is
cleaner (avoids frivolously using another QUEUE_FLAG).

Ming, I didn't add your Reviewed-by to "block: allow gendisk's
request_queue registration to be deferred" because it changed enough,
albeit for the better, that it is best for you to review again.

Thanks,
Mike

Mike Snitzer (4):
  block: only bdi_unregister() in del_gendisk() if !GENHD_FL_HIDDEN
  block: use queue_lock when clearing QUEUE_FLAG_REGISTERED in blk_unregister_queue
  block: allow gendisk's request_queue registration to be deferred
  dm: fix awkward and incomplete request_queue initialization
