As we have already found that the usage around memory.{emin, elow} has
many limitations, I think memory.{emin, elow} should be used for
memcg-tree internally only, that means they can only be used to
calculate the protection of a memcg in a specified memcg-tree but
should not be exposed to other MM parts.
