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?

Thanks.
