Subject: [PATCH 12/20] netfilter: ipset: The unnamed union initialization may lead to compilation error
From: Jozsef Kadlecsik <kadlec@...ckhole.kfki.hu>
The unnamed union should be possible to be initialized directly, but
unfortunately it's not so:
/usr/src/ipset/kernel/net/netfilter/ipset/ip_set_hash_netnet.c: In
function ?hash_netnet4_kadt?:
/usr/src/ipset/kernel/net/netfilter/ipset/ip_set_hash_netnet.c:141:
error: unknown field ?cidr? specified in initializer
