Subject: blk-mq: remove the error argument to blk_mq_complete_request
Date: Tue, 18 Apr 2017 08:52:21 -0700	[thread overview]
Message-ID: <20170418155229.5977-16-hch@bombadil.infradead.org> (raw)
In-Reply-To: <20170418155229.5977-1-hch@bombadil.infradead.org>

From: Christoph Hellwig <hch@lst.de>

Now that we always have a ->complete callback we can remove the direct
call to blk_mq_end_request, as well as the error argument to
blk_mq_complete_request.
