    Subject[PATCH 5.10 011/599] tools/virtio: fix virtio_test execution
    Date
    From: Stefano Garzarella <sgarzare@redhat.com>

    [ Upstream commit 32f1b53fe8f03d962423ba81f8e92af5839814da ]

    virtio_test hangs on __vring_new_virtqueue() because `vqs_list_lock`
    is not initialized.

    Let's initialize it in vdev_info_init().
