Correct. This was actually the last item of the TODO list. Anyway, I'm still considering if it's correct to move dirty pages when a task is migrated from a cgroup to another. Currently, dirty pages just remain in the original cgroup and are flushed depending on the original cgroup settings. That is not totally wrong... at least moving the dirty pages between memcgs should be optional (move_charge_at_immigrate?).
