Subject: [PATCH 02/12] block: don't init rq fields unnecessarily
Date: Thu, 23 Apr 2009 21:25:43 +0900	[thread overview]
Message-ID: <1240489553-15724-3-git-send-email-tj@kernel.org> (raw)
In-Reply-To: <1240489553-15724-1-git-send-email-tj@kernel.org>

blk_get_request() always returns properly zeroed requests.  Don't set
fields to zero/NULL unnecessarily.

[ Impact: cleanup ]
