From b3832c8b9839831288de7662b5e1b7f172a3e31d Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Thu, 29 Nov 2012 14:18:04 +1100 Subject: [PATCH] mempolicy: use N_MEMORY instead N_HIGH_MEMORY N_HIGH_MEMORY stands for the nodes that has normal or high memory. N_MEMORY stands for the nodes that has any memory. The code here need to handle with the nodes which have memory, we should use N_MEMORY instead.
