Julian Wiedmann 80bc97aa0a net/af_iucv: don't track individual TX skbs for TRANS_HIPER sockets ... Stop maintaining the skb_send_q list for TRANS_HIPER sockets. Not only is it extra overhead, but keeping around a list of skb clones means that we later also have to match the ->sk_txnotify() calls against these clones and free them accordingly. The current matching logic (comparing the skbs' shinfo location) is frustratingly fragile, and breaks if the skb's head is mangled in any sort of way while passing from dev_queue_xmit() to the device's HW queue. Also adjust the interface for ->sk_txnotify(), to make clear that we don't actually care about any skb internals.
