Getting pid from a sock?

[Phasip <phasip@xxxxxxxxx>]

Hello, i have tried to get pid from a struct sock without luck.
I tried

//It's named sock_i_pid coz i stole most of it from sock_i_uid.
int sock_i_pid(struct sock *sk)
{
        int pid;
        read_lock(&sk->sk_callback_lock);
        pid = sk->sk_socket ? sk->sk_socket->file->f_owner.pid : 0;
        read_unlock(&sk->sk_callback_lock);
        return pid;
}

But this always returns 0, even if i change it to set pid to 1 if
sk_socket doesn't exist.
