net: ipv4: avoid unused variable warning for sysctl (773daa3c) · Commits · 戴 / test

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. Fixes: ("net: ipv4: don't allow setting net.ipv4.route.min_pmtu below 68") Signed-off-by:
