Right, that would be the kind of optimization that would remove the
need for worrying about whether or not to account it. It would
probably mean creating some memcg-specific structures like
res-counters that could handle multiple values, since you'd need to
update both the kernel charge and the total charge, in this cgroup
*and* its ancestors.
