====================
Converting pernet_operations (part #11)

this series continues to review and to convert pernet_operations
to make them possible to be executed in parallel for several
net namespaces at the same time.

I thought last series was last, but there is one
new pernet_operations came to kernel. This is
udp_sysctl_ops, and here we convert it.

Also, David Howells acked rxrpc_net_ops, so I resend
the patch in case of it should be queued by patchwork:
