/* The SOCK_OPS"_SK" macro should be used when sock_ops->sk is not a
 * fullsock and its parent fullsock cannot be traced by
 * sk_to_full_sk().
 *
 * e.g. sock_ops->sk is a request_sock and it is under syncookie mode.
 * Its listener-sk is not attached to the rsk_listener.
 * In this case, the caller holds the listener-sk (unlocked),
 * set its sock_ops->sk to req_sk, and call this SOCK_OPS"_SK" with
 * the listener-sk such that the cgroup-bpf-progs of the
 * listener-sk will be run.
 *
 * Regardless of syncookie mode or not,
 * calling bpf_setsockopt on listener-sk will not make sense anyway,
 * so passing 'sock_ops->sk == req_sk' to the bpf prog is appropriate here.
