While testing various Kconfig options on another issue, I found that
the following one triggers as well on allmodconfig and nf_conntrack
disabled:
net/ipv4/netfilter/nf_dup_ipv4.c: In function ‘nf_dup_ipv4’:
net/ipv4/netfilter/nf_dup_ipv4.c:72:20: error: ‘nf_skb_duplicated’ undeclared (first use in this function)
if (this_cpu_read(nf_skb_duplicated))
[...]
net/ipv6/netfilter/nf_dup_ipv6.c: In function ‘nf_dup_ipv6’:
net/ipv6/netfilter/nf_dup_ipv6.c:66:20: error: ‘nf_skb_duplicated’ undeclared (first use in this function)
if (this_cpu_read(nf_skb_duplicated))
Fix it by including directly the header where it is defined.
Fixes: bbde9fc1824a ("netfilter: factor out packet duplication for IPv4/IPv6")

[ Don't know whether Dave wants to take it directly, or if it should
go via nf-next. I have one more build fix coming later tonight. Also
applies to net-next. ]
