Just so this discussion has some clarity. Nacked-by: "Eric W. Biederman" As a user visible entity I see nothing this container data structure helps solve it only muddies the waters and makes things more brittle. Embracing the complexity of namespaces head on tends to mean all of the goofy scary semantic corner cases are visible from the first version of the design, and so developers can't take short cuts that result in buggy kernel code that persists for decades. I am rather tired of finding and fixing those. Eric
