Subject: [PATCH 0/4] block: fix concurrent quiesce
Date: Wed,  3 Nov 2021 11:43:01 +0800	[thread overview]
Message-ID: <20211103034305.3691555-1-ming.lei@redhat.com> (raw)

Hi Jens,

Convert SCSI into balanced quiesce and unquiesce by using atomic
variable as suggested by James, meantime fix previous nvme conversion by
adding one new API because we have to wait until the started quiesce is
done.


Ming Lei (4):
  blk-mq: add one API for waiting until quiesce is done
  scsi: avoid to quiesce sdev->request_queue two times
  scsi: make sure that request queue queiesce and unquiesce balanced
  nvme: wait until quiesce is done
