The 0-day testing from Fenguang Wu issued the following warning:
net/netfilter/nft_reject.c: In function 'nft_reject_eval':
>> net/netfilter/nft_reject.c:37:14: warning: unused variable 'net' [-Wunused-variable]
struct net *net = dev_net((pkt->in != NULL) ? pkt->in : pkt->out);
This is due to the fact that if IPv6 is not build the variable is
indeed unused.
