Rewrite the AF_KCM transmission loop to send all the fragments in a single skb or frag_list-skb in one sendmsg() with MSG_SPLICE_PAGES set. The list of fragments in each skb is conveniently a bio_vec[] that can just be attached to a BVEC iter. Note: I'm working out the size of each fragment-skb by adding up bv_len for all the bio_vecs in skb->frags[] - but surely this information is recorded somewhere? For the skbs in head->frag_list, this is equal to skb->data_len, but not for the head. head->data_len includes all the tail frags too.
