In this case an application might be looking for an empty field as meaning the sockhad has no given address. I cannot apply this patch. People have repeatedly tried making changes to these networking socket procfs files, and I really wish people would stop trying to do so. If you want specific pieces of new information, extend the socket dumping facility that is actually extensible in a way which will not break existing applications, and that's netlink. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
