To drop strings that are only shown once anyway, such as:
static int __init ebtables_init(void)
{
int ret;
mutex_lock(&ebt_mutex);
list_add(&ebt_standard_target.list, &ebt_targets);
mutex_unlock(&ebt_mutex);
if ((ret = nf_register_sockopt(&ebt_sockopts)) < 0)
return ret;
-> printk(KERN_INFO "Ebtables v2.0 registered\n");
return 0;
}
