Oh, it's just based on activity. So, for example, iocost puts a cgroup on
its active list which is canned periodically when an IO is issued from an
inactive cgroup. If an active cgroup doesn't have any activity between two
scans, it becomes inactive and dropped from the list. drm can prolly use the
same approach?

Yeah, that sounds like a good idea.

Thanks.
