To merge it upstream, at a minimum we need NFSv4 working as well. It causes problems when version n+1 lacks features that version n has, especially in the presence of clients automatically negotiate up. I'm also inclined to think that making the various data structures and interfaces network-namespace-dependent is going to result in the cleaner and more useful solution. I probably should take that first cleanup patch at least, though. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
