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 block/blk-sysfs.c | 12 ++++++++---- block/genhd.c | 23 +++++++++++++++++++---- drivers/md/dm-core.h | 2 -- drivers/md/dm-rq.c | 11 ----------- drivers/md/dm.c | 41 ++++++++++++++++++++++------------------- include/linux/genhd.h | 5 +++++ 6 files changed, 54 insertions(+), 40 deletions(-) -- 2.15.0
