The ->page_offset of the frag gets applied two times. skb_dma_map_frag() already takes frag->page_offset into consideration, you then pass it in as the 'offset' argument and it then gets added to itself to compute th final offset. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
