Re: [PATCH] blk-mq: Make blk_mq_quiesce_tagset() hold the tag list mutex less long

Make sure that the tag_list_lock mutex is no longer held than necessary. This change reduces latency if e.g. blk_mq_quiesce_tagset() is called concurrently from more than one thread. This function is used by the NVMe core and also by the UFS driver.

Looks good to me.
