Subject: [PATCH 11/11] xfrm: fix unused variable warning if CONFIG_NETFILTER=n
Date: Fri, 29 May 2020 12:30:11 +0200 [thread overview]
Message-ID: <20200529103011.30127-12-steffen.klassert@secunet.com> (raw)
In-Reply-To: <20200529103011.30127-1-steffen.klassert@secunet.com>
From: Florian Westphal <fw@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.
Fixes: 2ab6096db2f1 ("xfrm: remove output_finish indirection from xfrm_state_afinfo")
