May be we should add some #ifdef CONFIG_PROC_FS because
proc_create_net* return NULL when PROC is not used. For example:
#ifdef CONFIG_PROC_FS
if (!proc_create_net...
goto err_vs;
if (!proc_create_net...
goto err_stats;
...
#endif
...
err:
#ifdef CONFIG_PROC_FS
+ remove_proc_entry("ip_vs_stats_percpu", ipvs->net->proc_net);
err_percpu:
+ remove_proc_entry("ip_vs_stats", ipvs->net->proc_net);
err_stats:
+ remove_proc_entry("ip_vs", ipvs->net->proc_net);
err_vs:
#endif
free_percpu(ipvs->tot_stats.cpustats);
return -ENOMEM;
}
