From f7b8988ff50d99c99746f65f420364e91362c065 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 1 Feb 2006 03:05:21 -0800 Subject: [PATCH] [PATCH] swsusp: do not change log level during suspend/resume Prevent the kernel from setting the log level to 10 unconditionally during suspend/resume which was needed in the past for debugging, but generally is undesirable.
