Now we're repeating the argument Frederic and Johannes had, so I'd
suggest going back the thread and reading the discussion and if you
still think using kmemcg is a bad idea, please explain why that is so.
For the specific point that you just raised, the scale tilted toward
thread/process count is a hacky and unreliable representation of
kernel memory resource than the other way around, at least back then.
If you think you can tilt it the other way, please feel free to try.
