Eric, what you gain with this patchset is, one very simple container subsystem can tie a container to a cpu, another can limit it's RSS, and suddenly you can mount -t container -o ns,rss,cpuwhatever ns /container And each virtual server you create by unsharing can get automatic cpu and rss controls. That is worthwhile imo. -serge _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxx https://lists.osdl.org/mailman/listinfo/containers
