Subject: [PATCH 27/47] nvme: do not restart the request timeout if we're
 resetting the controller
In-Reply-To: <1448090427-18749-1-git-send-email-hch@lst.de>
References: <1448090427-18749-1-git-send-email-hch@lst.de>
Message-ID: <1448090427-18749-28-git-send-email-hch@lst.de>

Otherwise we're never going to complete a command when it is restarted just
after we completed all other outstanding commands in nvme_clear_queue.
