Li Zefan ca0dde9717 memcg: take reference before releasing rcu_read_lock ... The memcg is not referenced, so it can be destroyed at anytime right after we exit rcu read section, so it's not safe to access it. To fix this, we call css_tryget() to get a reference while we're still in rcu read section. This also removes a bogus comment above __memcg_create_cache_enqueue().
