Subject: [PATCH 01/10] dont copy pages that arent RAM
Date: Mon, 05 Feb 2007 19:30:28 +0100 [thread overview]
Message-ID: <20070205185835.337746000@sipsolutions.net> (raw)
In-Reply-To: 20070205183026.989209000@sipsolutions.net
Pages that aren't RAM obviously cannot be saved during suspend-to-disk
so skip them.

Pavel Machek requested this be put into -mm for some more
testing although he says it seems fine.
