Subject: [PATCH 1/5] Container Freezer: Add TIF_FREEZE flag to all architectures
Date: Mon, 11 Aug 2008 16:53:24 -0700 [thread overview]
Message-ID: <20080811235324.279345521@us.ibm.com> (raw)
In-Reply-To: 20080811235323.872291138@us.ibm.com
This patch is the first step in making the refrigerator() available
to all architectures, even for those without power management.
The purpose of such a change is to be able to use the refrigerator()
in a new control group subsystem which will implement a control group
freezer.
