This is already queued in mmotm. == From 3b1bec1d07ba21339697f069acab47dae6b81097 Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> Date: Mon, 13 Jun 2011 09:32:28 +0900 Subject: [PATCH 1/5] memcg fix numa_stat permission
commit 406eb0c9b ("memcg: add memory.numastat api for numa statistics") adds memory.numa_stat file for memory cgroup. But the file permissions are wrong.
[kamezawa@bluextal linux-2.6]$ ls -l /cgroup/memory/A/memory.numa_stat ---------- 1 root root 0 Jun 9 18:36 /cgroup/memory/A/memory.numa_stat
This patch fixes the permission as
[root@bluextal kamezawa]# ls -l /cgroup/memory/A/memory.numa_stat -r--r--r-- 1 root root 0 Jun 10 16:49 /cgroup/memory/A/memory.numa_stat
