From b93196dc5af7729ff7cc50d3d322ab1a364aa14f Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Thu, 6 Dec 2012 10:04:04 +0800 Subject: [PATCH] net: fix some compiler warning in net/core/neighbour.c net/core/neighbour.c:65:12: warning: 'zero' defined but not used [-Wunused-variable] net/core/neighbour.c:66:12: warning: 'unres_qlen_max' defined but not used [-Wunused-variable] These variables are only used when CONFIG_SYSCTL is defined, so move them under #ifdef CONFIG_SYSCTL.
