The memory we used to hold the memcg arrays is currently accounted to the current memcg. But that creates a problem, because that memory can only be freed after the last user is gone. Our only way to know which is the last user, is to hook up to freeing time, but the fact that we still have some in flight kmallocs will prevent freeing to happen. I believe therefore to be just easier to account this memory as global overhead.
