I have a plan on how to make this work. A (very rough) draft
of the idea is on:
http://mail.nl.linux.org/linux-mm/2000-06/msg00296.html
Basically we want to:
1) try and make an educated guess as to how big the actual
working set of each process is
2) normalise the rss guarantees / limits to make sure that:
- the sum of all rss guarantees never exceeds physmem/N
- no rss limit is above ulimit.rss
- a user does not exceed his/her rss quota
- a user does not get below his/her rss guarantee
regards,
Rik
