Message-ID: <486E1160.3030003@openvz.org>

Subject: [PATCH 2/4] MIB: add struct net to UDP_INC_STATS_BH
Two special cases here - one is rxrpc - I put init_net there
explicitly, since we haven't touched this part yet. The second
place is in __udp4_lib_rcv - we already have a struct net there,
but I have to move its initialization above to make it ready
at the "drop" label.
