dm rq: add DM_MAPIO_DELAY_REQUEUE to delay requeue of blk-mq requests Otherwise blk-mq will immediately dispatch requests that are requeued via a BLK_MQ_RQ_QUEUE_BUSY return from blk_mq_ops .queue_rq. Delayed requeue is implemented using blk_mq_delay_kick_requeue_list() with a delay of 5 secs. In the context of DM multipath (all paths down) it doesn't make any sense to requeue more quickly.
