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?).
Thanks for your ack and the detailed review!
