From d287483d6d7a2d5b313aee155285f89b57d9cd4a Mon Sep 17 00:00:00 2001 From: Alasdair G Kergon Date: Wed, 8 Nov 2006 17:44:43 -0800 Subject: [PATCH] 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.)
