[0 - 2] +Also, we can reproduce it by a program in [3]. + +In the commit, we delay freeing ipv6_pinfo.pktoptions from sk->destroy() +to sk->sk_destruct(), so sk->sk_forward_alloc is no longer zero in +inet_csk_destroy_sock(). + +The same check has been in inet_sock_destruct() from at least v2.6, +we can just remove the WARN_ON_ONCE().
