Subject: [PATCH 14/47] nvme: move nvme_error_status to common code
Date: Sat, 21 Nov 2015 08:19:54 +0100
Message-ID: <1448090427-18749-15-git-send-email-hch@lst.de> (raw)
In-Reply-To: <1448090427-18749-1-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.
