Now the queue won't be stopped via blk_mq_quiesce_queue(), so why do
you add blk_mq_kick_requeue_list() here?
I think you're right.
We now quiesce the queue and fast fail inflight io, in
nvme_complete_rq we call blk_mq_requeue_request with
!blk_mq_queue_stopped(req->q) which is now true.
So the requeue_work is triggered and requeue the request,
and when we unquiesce we simply run the hw queues again.
If we were to call it with !blk_queue_quiesced(req->q)
I think it would be needed though...
