The way nsproxy is structured, its all pointers to actual namespace (or in case of rcfs patch) resource objects. This lets namespaces objects be in a flat hierarchy while resource objects are in tree-like hierarchy. nsproxy itself doesnt decide any hierarchy. Its those objects pointed to by nsproxy which can form different hierarchies. In fact the rcfs patches allows such a combination afaics. > > on every limit accounting or check?

A rcu_read_lock() should be required, which is not that expensive. -- Regards, vatsa _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxx https://lists.osdl.org/mailman/listinfo/containers
