With this patch applied, a sample output from root cgroup.stat file
was shown below.

	nr_descendants 54
	nr_dying_descendants 44
	nr_cpuset 1
	nr_cpu 40
	nr_io 40
	nr_memory 54
	nr_dying_memory 44
	nr_perf_event 55
	nr_hugetlb 1
	nr_pids 54
	nr_rdma 1
	nr_misc 1
So, css may be too specific a name but this looks a bit disorganized. How
about using controller as the common prefix? Maybe something like:

	nr_controllers_cpu 40
	nr_controllers_io 40
	nr_controllers_memory 54
	nr_controller_perf_event 55
	...
	nr_dying_controllers_memory 44

If controllers is too long, we can shorten it somehow or use subsys, maybe?

I think "controllers" is too long. I am fine with "subsys". Will make change in the next version.

Thanks,
Longman
