Jan Musial 6c6bc95b29 Use blk_plug mechanism in bottom block adapter ... This is a suboptimal solution to CAS on top of MD RAID1 device. If using only submit_bio API RAID1 would process all IOs in single thread. Plugging bypasses this thread and processess IOs in blk_finish_plug caller context improving performance drastically. Testing showed no negative impact to other usecases and it's a thing that Linux does in AIO, so it's vetted and proven to work.
