Hi all,

After merging the netfilter-next tree, today's linux-next build (x86_64
allmodconfig) produced these warnings:

In file included from <command-line>:
include/uapi/linux/netfilter_ipv6/ip6t_LOG.h:5:2: warning: #warning "Please update iptables, this file will be removed soon!" [-Wcpp]
 #warning "Please update iptables, this file will be removed soon!"
  ^~~~~~~
