Date: Mon, 2 Nov 2009 00:11:02 +0900 (JST) From: KOSAKI Motohiro <kosaki.motohiro@...fujitsu.com> To: LKML <linux-kernel@...r.kernel.org> Cc: kosaki.motohiro@...fujitsu.com, "Rafael J. Wysocki" <rjw@...k.pl>, Rik van Riel <riel@...hat.com>, linux-mm <linux-mm@...ck.org>, Andrew Morton <akpm@...ux-foundation.org>, Christoph Lameter <cl@...ux-foundation.org>, Mel Gorman <mel@....ul.ie> Subject: [PATCHv2 3/5] vmscan: Stop zone_reclaim()'s wrong swap_cluster_max usage In old days, we didn't have sc.nr_to_reclaim and it brought sc.swap_cluster_max misuse. huge sc.swap_cluster_max might makes unnecessary OOM and no performance benefit. Now, we can remove above dangerous one.
