Subject: [PATCH 7/7] hang and lockup detection menu
Date: Tue, 07 May 2013 13:46:52 -0700 [thread overview]
Message-ID: <20130507204652.3BA40001@viggo.jf.intel.com> (raw)
In-Reply-To: <20130507204642.D010DDC1@viggo.jf.intel.com>
From: Dave Hansen <dave.hansen@linux.intel.com>
The hard/softlockup and hung-task entries take up 6 lines
of screen real-estate when enabled. I bet folks don't
mess with these _that_ often, so move them in a group
down a level.
