From: Wanpeng Li <liwp@xxxxxxxxxxxxxxxxxx>
Since hierachical_memory_limit shows "of bytes of memory limit with
regard to hierarchy under which the memory cgroup is", the count should
calculate max hierarchy limit when use_hierarchy in order to show hierarchy
subtree limit. hierachical_memsw_limit is the same case.
