So aside from having (RO) links in thread groups for system controllers,
we could also have a ${controller}_parent link back to whatever group is
the actual parent for that specific controller's view.
So then your B's memcg_parent would point to A, not T.
But I feel this is all superfluous window dressing; but if you want to
clarify the filesystem interface, this could be something to consider.
