There's an ARRAY_SIZE(smc_table) - 1 in smc_sysctl_net_init, shouldn't
the -1 be removed like you did in other patches?


int __net_init smc_sysctl_net_init(struct net *net)
{
	struct ctl_table *table;

	table = smc_table;
	if (!net_eq(net, &init_net)) {
		int i;

		table = kmemdup(table, sizeof(smc_table), GFP_KERNEL);
		if (!table)
			goto err_alloc;

		for (i = 0; i < ARRAY_SIZE(smc_table) - 1; i++)
			table[i].data += (void *)net - (void *)&init_net;
	}

	net->smc.smc_hdr = register_net_sysctl_sz(net, "net/smc", table,
						  ARRAY_SIZE(smc_table));
