Hi,
The 1st patch fixes one kernel oops triggered by IOs vs. deleting SCSI
device, and this issue can be triggered in less than 1min on scsi_debug.
The other 5 patch fixes recent Yi Zhang's reports about his NVMe stress
tests, most of them are related with switching io sched, NVMe reset or
updating nr_hw_queues.
Thanks,
Ming

blk-mq: quiesce queue before freeing queue
blk-mq: support concurrent blk_mq_quiesce_queue()
blk-mq: quiesce queue during switching io sched and updating
nr_requests
blk-mq: avoid to map CPU into stale hw queue
blk-mq: fix race between updating nr_hw_queues and switching io sched
nvme: remove .init_request callback
