Hmm... Perhaps I should move the used arrays into the "struct
virtio_device" and guarantee that the id (returned by add_*buf) is an
index into that. Then we can trivially add a corresponding bit array.
That may force the virtio backend to do things it doesn't want to.
This also makes the "id" easier to use from the driver side: if we add a
"max_id" field it can size its own arrays if it wants to. Gets rid of
the linked-list in the block driver...
How about
struct virtio_completion {
unsigned long length;
void *data;
};
int virtio_complete(struct virtio_completion *completions, int nr);
where 'data' is an opaque pointer passed by the device during add_*buf()?
