Subject: [PATCH 3/8] nvme-loop: quiesce admin_q instead of stopping hw queues
Date: Tue, 4 Jul 2017 10:55:07 +0300 [thread overview]
Message-ID: <1499154912-10420-4-git-send-email-sagi@grimberg.me> (raw)
In-Reply-To: <1499154912-10420-1-git-send-email-sagi@grimberg.me>
Before we iterate over the tags, we need to make sure that
no inflight requests are being queued, so use quiesce
helper for that.
