block: reorganize queue draining Reorganize queue draining related code in preparation of queue exit changes. * Factor out actual draining from elv_quiesce_start() to blk_drain_queue(). * Make elv_quiesce_start/end() responsible for their own locking. * Replace open-coded ELVSWITCH clearing in elevator_switch() with elv_quiesce_end(). This patch doesn't cause any visible functional difference. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>
