From b6b6cc72bc404c952968530d7df4c3a4ab82b65b Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Mon, 7 Apr 2014 15:37:44 -0700 Subject: [PATCH] memcg: do not replicate get_mem_cgroup_from_mm in __mem_cgroup_try_charge __mem_cgroup_try_charge duplicates get_mem_cgroup_from_mm for charges which came without a memcg. The only reason seems to be a tiny optimization when css_tryget is not called if the charge can be consumed from the stock. Nevertheless css_tryget is very cheap since it has been reworked to use per-cpu counting so this optimization doesn't give us anything these days. So let's drop the code duplication so that the code is more readable.
