Subject: [PATCH V2 0/4] nvme: fix two kinds of IO hang from removing NSs
Date: Tue, 20 Jun 2023 09:33:45 +0800	[thread overview]
Message-ID: <20230620013349.906601-1-ming.lei@redhat.com> (raw)

Hello,

The 1st three patch fixes io hang when controller removal interrupts error
recovery, then queue is left as frozen.

The 4th patch fixes io hang when controller is left as unquiesce.

V2:
	- don't unfreeze queue which isn't frozen for avoiding warning from
	percpu_ref_resurrect() 

Ming Lei (4):
  blk-mq: add API of blk_mq_unfreeze_queue_force
  nvme: add nvme_unfreeze_force()
  nvme: unfreeze queues before removing namespaces
  nvme: unquiesce io queues when removing namespaces
