From 773daa3caf5d3f87fdb1ab43e9c1b367a38fa394 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 28 Feb 2018 14:32:48 +0100 Subject: net: ipv4: avoid unused variable warning for sysctl The newly introudced ip_min_valid_pmtu variable is only used when CONFIG_SYSCTL is set: net/ipv4/route.c:135:12: error: 'ip_min_valid_pmtu' defined but not used [-Werror=unused-variable] This moves it to the other variables like it, to avoid the harmless warning.
