Yeah, the great pain of full hierarchy support is one of the reasons
why I keep thinking about supporting mapping to flat hierarchy. Full
hierarchy could be too painful and not useful enough for some
controllers. Then again, cpu and memcg already have it and according
to Vivek blkcg also had a proposed implementation, so maybe it's okay.
Let's see.
Thanks.
