    lguest: fix block request handling in example launcher. · c0316a94
    Rusty Russell authored
    virtio requests are scatter-gather-style descriptors, but no
    assumptions should be made about the layout.  lguest was lazy here,
    but saved by the fact that the network device hands all requests to
    tun (which does it correctly) and console and random devices simply
    use readv and writev.
    
    Block devices, however, are broken: we convert to iovecs internally,
    just make sure we handle the correctly.
