From 47185052165a4c5de0a461018238375dd982c2ec Mon Sep 17 00:00:00 2001 From: KOSAKI Motohiro Date: Tue, 26 Oct 2010 14:21:43 -0700 Subject: [PATCH] vmscan: remove dead code in shrink_inactive_list() After synchrounous lumpy reclaim, the page_list is guaranteed to not have active pages as page activation in shrink_page_list() disables lumpy reclaim. Remove the dead code.
