From 8798cee2f90292ca4ca84baccc757e4d06f8797f Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Fri, 20 Dec 2013 14:54:11 +0000 Subject: Revert "mm: page_alloc: exclude unreclaimable allocations from zone fairness policy" This reverts commit 73f038b863df. The NUMA behaviour of this patch is less than ideal. An alternative approch is to interleave allocations only within local zones which is implemented in the next patch.
