The attached trivial patch (generated against davem/net-next-2.6 as of
this morning) avoids this compiler warning:
../src/process-manager/linux/net/netfilter/nf_conntrack_proto_dccp.c: In
function ‘dccp_net_exit’:
../src/process-manager/linux/net/netfilter/nf_conntrack_proto_dccp.c:845: error: unused variable ‘dn’
