If you want to dump prohibit/blackhole entry, then you have to check for null_entry, and rt->dst.error check is still needed because we could return error on other normal entries too, IOW, your v2 is correct if dumping prohibit/blackhole is expected. I thought we don't dump them. I am not sure about the behavior either.
