Don't think so. It is absolutely possible, especially over loopback. It can happen on the send side for any device which indicates the NETIF_F_HIGHDMA capability, and because loopback indicates this feature this means we'll see such highmem pages in packets on receive too. There is thus also nothing preventing a real hardware device from feeding highmem packets into the networking stack. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
