Based on the discussions at OLS yesterday, the consensus was to try an
integrated pagecache controller along with RSS controller under the
same usage limit.
This
page_container list only once
independent of repeated calls from pagecache, swapcache and mmap to RSS.
No setup patch is required since rss_limit and rss_usage has been generalised
as the resource counter for pagecache as well.

Hi Paul,
In [patch 3/7] Containers (V8): Add generic multi-subsystem API to
containers, you have forcefully enabled interrupt in
