From mboxrd@z Thu Jan 1 00:00:00 1970 From: NeilBrown Subject: [PATCH 005 of 29] md: use bio_endio instead of a call to bi_end_io Date: Fri, 27 Jun 2008 16:49:50 +1000 Message-ID: <1080627064950.10364@suse.de> References: <20080627164503.9671.patches@notabene> Return-path: Sender: linux-raid-owner@vger.kernel.org To: Andrew Morton Cc: linux-raid@vger.kernel.org, linux-kernel@vger.kernel.org, Mikulas Patocka List-Id: linux-raid.ids Turn calls to bi->bi_end_io() into bio_endio(). Apparently bio_endio does exactly the same error processing as is hardcoded at these places. bio_endio() avoids recursion (or will soon), so it should be used.
