Patch 1/2 is a minor cleanup for kmem accouting path. Patch 2/2 optimizes some hot paths by making cgroup_memory_noswap a static key, benchmark shows swap paths now have a ~5% lower overhead. Update from V1: - Collect Acked-by for patch 2/2 from Michal Hocko, Thanks! - Simplify patch 1/1, don't drop mem_cgroup_kmem_disabled and only change one call site as a minor clean up, update commit message for patch 2/2, as suggested by Michal Hocko.
