From 05b4877f6a4f1ba4952d1222213d262bf8c132b7 Mon Sep 17 00:00:00 2001 From: "Srivatsa S. Bhat" Date: Fri, 17 Feb 2012 23:39:51 +0100 Subject: PM / Hibernate: Enable usermodehelpers in hibernate() error path If create_basic_memory_bitmaps() fails, usermodehelpers are not re-enabled before returning. Fix this. And while at it, reword the goto labels so that they look more meaningful. Signed-off-by: Srivatsa S. Bhat Cc: stable@vger.kernel.org Signed-off-by: Rafael J.
