[PATCH] memcg: fix mm/memcontrol.c build error against linux-next

From: Wanpeng Li
Date: Sun Jul 22 2012 - 23:27:59 EST


As Fengguang Wu reported, linux-next failed to build with

tree: git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git akpm
head: 37e2ad4953983527f7bdb6831bf478eedcc84082
commit: 442d53f161093de78f0aafcd3ec2a6345de42890 [164/309] memcg: add mem_cgroup_from_css() helper

mem_cgroup_from_css() is defined inside CONFIG_MEMCG_KMEM and used
outside of it, move mem_cgroup_from_css() out of the #ifdef
CONFIG_MEMCG_KMEM can address this issue.
