	Visually, they should look like this:

        if (!proc_create_net("ip_vs", 0, ipvs->net->proc_net,
                             &ip_vs_info_seq_ops, sizeof(struct ip_vs_iter)))
                goto err_vs;
        if (!proc_create_net_single("ip_vs_stats", 0, ipvs->net->proc_net,
                                    ip_vs_stats_show, NULL))
                goto err_stats;
        if (!proc_create_net_single("ip_vs_stats_percpu", 0,
                                    ipvs->net->proc_net,
                                    ip_vs_stats_percpu_show, NULL))
                goto err_percpu;

	The first one explained:

<1  TAB>if (!proc_create_net("ip_vs", 0, ipvs->net->proc_net,
<  open parenthesis is here  ^ and all next lines align to first parameter>
<1  TAB><1  TAB><1 TAB><5 SP>&ip_vs_info_seq_ops, sizeof(struct ip_vs_iter)))
<1  TAB><1  TAB>goto err_vs;
