David S. Miller 689be43945 [NET]: Remove gratuitous use of skb->tail in network drivers. ... Many drivers use skb->tail unnecessarily. In these situations, the code roughly looks like: dev = dev_alloc_skb(...); [optional] skb_reserve(skb, ...); ... skb->tail ... But even if the skb_reserve() happens, skb->data equals skb->tail. So it doesn't make any sense to use anything other than skb->data in these cases. Another case was the s2io.c driver directly mucking with the skb->data and skb->tail pointers. It really just wanted to do an skb_reserve(), so that's what the code was changed to do instead. Another reason I'm making this change as it allows some SKB cleanups I have planned simpler to merge. In those cleanups, skb->head, skb->tail, and skb->end pointers are removed, and replaced with skb->head_room and skb->tail_room integers. Signed-off-by: David S.
