Message-Id: <1070927072024.4225@suse.de>
Date: Thu, 27 Sep 2007 17:20:24 +1000
From: NeilBrown <neilb@...e.de>
To: Jens Axboe <jens.axboe@...cle.com>
Cc: linux-kernel@...r.kernel.org
Subject: [PATCH 004 of 4] Drop 'size' argument from bio_endio and bi_end_io.
As bi_end_io is only called once when the reqeust is complete,
the 'size' argument is now redundant. Remove it.
Now there is no need for bio_endio to subtract the size completed
from bi_size. So don't do that either.
While we are at it, change bi_end_io to return void.
Signed-off-by: Neil Brown <neilb@...e.de>
