Subject: [PATCH 01/11] nbd: don't clear rq->sector and nr_sectors unnecessarily
Date: Mon,  4 May 2009 16:58:37 +0900	[thread overview]
Message-ID: <1241423927-11871-2-git-send-email-tj@kernel.org> (raw)
In-Reply-To: <1241423927-11871-1-git-send-email-tj@kernel.org>

There's no reason to clear rq->sector and nr_sectors after calling
blk_rq_init().  They're guaranteed to be clear.  Drop unnecessary
clearing.

[ Impact: cleanup ]
