Message-Id: <1080114014549.20399@suse.de>
Date: Mon, 14 Jan 2008 12:45:49 +1100
From: NeilBrown <neilb@...e.de>
To: Andrew Morton <akpm@...ux-foundation.org>
Cc: linux-raid@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: [PATCH 005 of 6] md: Change ITERATE_RDEV to rdev_for_each
as this is morein line with common practice in the kernel.
Also swap the args around to be more like list_for_each.
Signed-off-by: Neil Brown <neilb@...e.de>
