(It can be considered as extended ulimit.) But if you'd like to add relationship between virtual-limit/memory-usage-limit, please take care to make it clear that relationship is reaseonable. - memory-usage includes page-cache. - memory-usage doesn't include hugepages. - How to treat MAP_NORESERVE is depends on over-commit-memory type. how cgroup does ? - shared memory will be conuted per mmap.
