  SUNRPC: Don't return EPROTONOSUPPORT in svc_register()'s helpers
  SUNRPC: Use IPv4 loopback for registering AF_INET6 kernel RPC services
  SUNRPC: Set IPV6ONLY flag on PF_INET6 RPC listener sockets
  NFS: Revert creation of IPv6 listeners for lockd and NFSv4 callbacks
  SUNRPC: Remove @family argument from svc_create() and svc_create_pooled()
