From: Kairui Song <kasong@xxxxxxxxxxx> Patch 1/2 changes the behavior of kmem accounting a bit, making it either globally enabled or globally disabled by boot params and no longer affected by the creation of the first non-root cgroup. This might be a bit arguable though. Patch 2/2 optimizes some hot paths by making cgroup_memory_noswap a static key, benchmark shows swap paths now have a ~4% lower overhead.
