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 block/blk-mq.c | 28 +++++++++++++------ drivers/nvme/host/core.c | 4 +++ drivers/scsi/scsi_lib.c | 55 +++++++++++++++++++++++--------------- include/linux/blk-mq.h | 1 + include/scsi/scsi_device.h | 1 + 5 files changed, 59 insertions(+), 30 deletions(-) -- 2.31.1
