Message-ID: <20061107183046.GD6993@agk.surrey.redhat.com> Date: Tue, 7 Nov 2006 18:30:46 +0000 From: Alasdair G Kergon <agk@...hat.com> To: Andrew Morton <akpm@...l.org> Cc: linux-kernel@...r.kernel.org, dm-devel@...hat.com Subject: [PATCH 2.6.19 2/5] dm: suspend: fix error path If the device is already suspended, just return the error and skip the code that would incorrectly wipe md->suspended_bdev. (This isn't currently a problem because existing code avoids calling this function if the device is already suspended.)
