Subject: [PATCH][3/3] mm: swsusp post resume aggressive swap prefetch
Date: Mon, 20 Mar 2006 02:34:00 +1100 [thread overview]
Message-ID: <200603200234.01472.kernel@kolivas.org> (raw)
Swsusp reclaims a lot of memory during the suspend cycle and can benefit
from the aggressive_swap_prefetch mode immediately upon resuming.
