Michael S. Tsirkin 9c378abc5c virtio-balloon: fix add/get API use ... Since ee7cd8981e 'virtio: expose added descriptors immediately.', in virtio balloon virtqueue_get_buf might now run concurrently with virtqueue_kick. I audited both and this seems safe in practice but this is not guaranteed by the API. Additionally, a spurious interrupt might in theory make virtqueue_get_buf run in parallel with virtqueue_add_buf, which is racy. While we might try to protect against spurious callbacks it's easier to fix the driver: balloon seems to be the only one (mis)using the API like this, so let's just fix balloon.
