From fc1b2b568a2a9c2f0a46d23a7b922d67ce2b38f5 Mon Sep 17 00:00:00 2001 From: Kamezawa Hiroyuki Date: Sat, 21 Jul 2012 10:53:55 +1000 Subject: [PATCH] memcg: rename MEM_CGROUP_CHARGE_TYPE_MAPPED as MEM_CGROUP_CHARGE_TYPE_ANON Now, in memcg, 2 "MAPPED" enum/macro are found MEM_CGROUP_CHARGE_TYPE_MAPPED MEM_CGROUP_STAT_FILE_MAPPED Thier names looks similar to each other but the former is used for accounting anonymous memory. rename it as TYPE_ANON.
