@Jonas - Thanks, will remove the lines you suggested.
@Aggelos - I will make the change from cout to count. Actually, I wrote the code
and tested but the changes were merged into my master. So, unable to get the
diff, I forked a node in my new Dragonfly VM and wrote it.
Also wanted to discuss about the division. I got your point, I am doing
something wrong, following would be a possible solution.
What I thought, If their is a Process P' and assuming it has only a single
object O'. Suppose, O' has 1000 pages in memory i.e. the resident page count.
Now, if all this 1000 pages each have pv_list_count 3 i.e. each page is shared
by 3 processes (2 processes apart from P'). So the agg_pv_list_count will be
3000 and the resident_page_count is 1000.
Now if I divide agg_*/resident_* it will be 3000/1000 i.e. I get that approx 3
process are sharing that object and should then divide res*/3 to get the
proportional RSS.
