Are there any place where all 48 bytes of cb are used?Yes, but on in qdisc layer. struct tcp_skb_cb is known to be 44 bytes (when IPv6 is enabled) In qdisc layer, we use a small part of it, for the moment.quoted
I wouldn't mind if 'time_to_send' became a separate skb field for a more generic 'time_in_queue'...This wont happen. As I posted in an earlier patch, this can be added in "struct qdisc_skb_cb"
Ah... this patch? http://patchwork.ozlabs.org/patch/125329/ I liked what I saw then, but nobody chirped up to review it... I guess I know what I'm doing this weekend.
