Subject: [RFC][PATCH -mm 1/2] Freezer: Be more verbose
Date: Wed, 25 Jul 2007 14:03:14 +0200 [thread overview]
Message-ID: <200707251403.15078.rjw@sisk.pl> (raw)
In-Reply-To: <200707251401.48340.rjw@sisk.pl>
From: Rafael J. Wysocki <rjw@sisk.pl>
Increase the freezer's verbosity a bit, so that it's easier to read problem
reports related to it.
This is necessary for the next patch.
