though the 80-column comment omits to say "resident set" before "size",
I believe they'd be expected to account (subdivided) resident set sizes?
your calculation is not rss nor not integral.
physical mem? i.e. not swapped out.
Yes.
Plus, 'integral' mean "tick * rss". but in dyntick environment, per tick statistics is not
so easy nor low cost.
So, if I want to get those rss statistics, I have to add some more
mm_counter by myself? I only find file_rss and anon_rss in mm_struct.
Hmm..
I doubt nobody use such statistics. if nobody explain real world usage, I oppose to add
new counter overhead.
