...nges: 1) struct virtio_device has a "lock" and "priv" fields (the latter for the driver to use, esp from callbacks). 2) add_outbuf and add_inbuf take a cb function ptr and void *, rather than a used pointer. 3) lengths of buffers must now fit in an unsigned int, not long. 4) the virtio_sync wrapper is gone. Block driver changes (+30 lines) 1) Convert to callbacks not interrupt. 2) Ensure both outbuf & inbuf have been used up before finishing request. This avoids potential remote access to freed memory. Net driver changes (+6 lines) 1) Convert to callbacks. 2) Store id in skb-&g...
