+bool tcp_ao_ignore_icmp(struct sock *sk, int type, int code)const struct sock *sk ?Well, I can't really: atomic64_inc(&ao->counters.dropped_icmp)
I think we could, because this would still work. struct tcp_ao_info *ao; // This is rw object ao = rcu_dereference(tcp_sk(sk)->ao_info); This helper looks to accept unlocked sockets, so marking them const would avoid mistakes in the future.
