[NET]: Make core networking code use seq_open_private
This concerns the ipv4 and ipv6 code mostly, but also the netlink and unix sockets. The netlink code is an example of how to use the __seq_open_private() call - it saves the net namespace on this private. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.
