I guess patches like these should be reverted then ?
e3f0b86b996d
"ipv6: Use BUG_ON"
8242fc33925c
"net: ipv6: Use BUG_ON"
Some existing BUG_ON() as well ? ; eg second one in net/decnet/dn_rules.c:
void __init dn_fib_rules_init(void)
{
dn_fib_rules_ops =
fib_rules_register(&dn_fib_rules_ops_template, &init_net);
BUG_ON(IS_ERR(dn_fib_rules_ops));
BUG_ON(fib_default_rule_add(dn_fib_rules_ops, 0x7fff,
RT_TABLE_MAIN, 0));
}
Regards,
Fabian
