Subject: [PATCH 0/3] block: keep quiesce & unquiesce balanced for scsi/dm
Date: Thu, 21 Oct 2021 22:59:15 +0800 [thread overview]
Message-ID: <20211021145918.2691762-1-ming.lei@redhat.com> (raw)
Hello Jens,
Recently we merge the patch of e70feb8b3e68 ("blk-mq: support concurrent queue
quiesce/unquiesce") for fixing race between driver and block layer wrt.
queue quiesce.
Yi reported that srp/002 is broken with this patch, turns out scsi and
dm don't keep the two balanced actually.
So fix dm and scsi and make srp/002 pass again.
Ming Lei (3):
scsi: avoid to quiesce sdev->request_queue two times
scsi: make sure that request queue queiesce and unquiesce balanced
dm: don't stop request queue after the dm device is suspended
