OK, will do.

Great :-)

tcp_clean_rtx_queue() is automatically inlined into tcp_ack() by gcc.
That's:
tcp_ack():        /* See if we can take anything off of the retransmit queue. */        flag |= tcp_clean_rtx_queue(sk, prior_fackets);
tcp_clean_rtx_queue():        tcp_verify_left_out(tp);    <=========== Here
        if (skb && (TCP_SKB_CB(skb)->sacked & TCPCB_SACKED_ACKED))                flag |= FLAG_SACK_RENEGING;

Thanks.
