Hi Rusty,

After merging the virtio tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/net/virtio_net.c: In function 'vq2txq':
drivers/net/virtio_net.c:150:2: error: implicit declaration of function 'virtqueue_get_queue_index' [-Werror=implicit-function-declaration]

Caused by commit 986a4f4d452d ("virtio_net: multiqueue support") from the
net-next tree interacting with commit 105e892960e1 ("virtio: move
queue_index and num_free fields into core struct virtqueue") from the
virtio tree.

I applied the patch below and can carry it as necessary.
