[PATCH 0/2] mm: memcontrol: cleanup and optimize for accounting params

[Kairui Song]

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.
