Subject: [PATCH 14/47] nvme: move nvme_error_status to common code
Date: Fri, 20 Nov 2015 17:35:09 +0100 [thread overview]
Message-ID: <1448037342-18384-15-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1448037342-18384-1-git-send-email-hch@lst.de>
And mark it inline so that we don't slow down the completion path by
having to turn it into a forced out of line call.
