From: Florian Westphal <f...@strlen.de> After recent change 'x' is only used when CONFIG_NETFILTER is set:
net/ipv4/xfrm4_output.c: In function '__xfrm4_output': net/ipv4/xfrm4_output.c:19:21: warning: unused variable 'x' [-Wunused-variable] 19 | struct xfrm_state *x = skb_dst(skb)->xfrm; Expand the CONFIG_NETFILTER scope to avoid this.
