commit b93196dc5af7729ff7cc50d3d322ab1a364aa14f Author: Cong Wang <amwang@redhat.com> Date: Thu Dec 6 10:04:04 2012 +0800
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.
