OpenVZ works w/o it. This idea is come from by Glauber's comments for my previous patches which bind quota to cgroup, and per my try out, it really works to some extents. > It sounds as too strict use case limitation. Or do I understand your patchset description wrong? According to my understood, bind quota to mount namespace is another quota strategy, and container is a potential user case, maybe could be used for other things. I certainly will study openVZ's quota code.
