Date: Wed, 6 Dec 2006 17:01:05 +0000 From: Andy Whitcroft <apw@...dowen.org> To: Andrew Morton <akpm@...l.org>, linux-mm@...ck.org Cc: Peter Zijlstra <a.p.zijlstra@...llo.nl>, Mel Gorman <mel@....ul.ie>, Andy Whitcroft <apw@...dowen.org>, linux-kernel@...r.kernel.org Subject: [PATCH 4/4] lumpy take the other active inactive pages in the area lumpy: take the other active/inactive pages in the area When we scan an order N aligned area around our tag page take any other pages with a matching active state to that of the tag page. This will tend to demote areas of the order we are interested from the active list to the inactive list and from the end of the inactive list, increasing the chances of such areas coming free together.
