The main changes since the last patchset are: 1) removal of the -4 and -6 options. The preferred way to disable address families for now will be to configure /etc/netconfig. It's probably better not to add new command line options until there is a clear need for them. Since I'm not adding new options, I've dropped the manpage patch too. We may still want a manpage update eventually to discuss how one should disable address families for nfsd. 2) Fixed the error handling when ipv6.ko is blacklisted. The earlier patchset would cause the program to error out when it couldn't create a socket for an address family. Now, as long as the program succeeds in creating sockets for at least one address family it will declare success. It will however, log an error that it was unable to create the socket for the other. I think the set is bisectable, but have only really tested the final result. I've also tested the final result when built with tirpc enabled and disabled, and ipv6 enabled and disabled. I've also tested this with a rpc.nfsd built for IPv6 on a host that has ipv6.ko blacklisted. Most of the testing I've done has been by watching the program under strace. Since most of the kernel work for IPv6 support hasn't made it to mainline, it's a little difficult to do much testing of this beyond that.
