Date: Fri, 13 Jun 2014 16:37:09 +0900 From: Simon Horman <horms@...ge.net.au> To: Pablo Neira Ayuso <pablo@...filter.org> Cc: lvs-devel@...r.kernel.org, netdev@...r.kernel.org, netfilter-devel@...r.kernel.org, Wensong Zhang <wensong@...ux-vs.org>, Julian Anastasov <ja@....bg>, Simon Horman <horms@...ge.net.au> Subject: [PATCH] ipvs: stop tot_stats estimator only under CONFIG_SYSCTL From: Julian Anastasov <ja@....bg> The tot_stats estimator is started only when CONFIG_SYSCTL is defined. But it is stopped without checking CONFIG_SYSCTL. Fix the crash by moving ip_vs_stop_estimator into ip_vs_control_net_cleanup_sysctl. The change is needed after commit 14e405461e664b ("IPVS: Add __ip_vs_control_{init,cleanup}_sysctl()") from 2.6.39.
