[PATCH 0/9] virtio: new API for addition of buffers, scatterlist changes
...s easiest
to just switch to the new API, just like for virtio-scsi. For virtio-net
the ending marker must be reset after calling virtqueue_add_buf, in
preparation for the next usage of the scatterlist. Other drivers are
safe already, but many can be converted to the "fast-path" function
virtqueue_add_buf_single suggested by mst; this is done in patch 8.
Compared to the RFC, I have moved the state of virtqueue_add_sg into
struct vring_desc, and I replaced virtqueue_add_sg_single with
virtqueue_add_buf_single. I renamed the "count" and "count_sg"
to "nents" and "nsg"...
