Chao Leng 414dd48e88 blk-mq: add tagset quiesce interface ... Drivers that have shared tagsets may need to quiesce potentially a lot of request queues that all share a single tagset (e.g. nvme). Add an interface to quiesce all the queues on a given tagset. This interface is useful because it can speedup the quiesce by doing it in parallel. Because some queues should not need to be quiesced (e.g. the nvme connect_q) when quiescing the tagset, introduce a QUEUE_FLAG_SKIP_TAGSET_QUIESCE flag to allow this new interface to ski quiescing a particular queue.
