2585     * draining all requests on it first, but some qemu-iotests cases want to
2586     * issue multiple aio_read/write requests and expect them to complete in

2592     * anything else run before we have revoken them to avoid race conditions.
2593     *
2594     * What happens now is that command() in qemu-io-cmds.c can extend the
2595     * permissions if necessary for the qemu-io command. And they simply stay
2596     * extended, possibly resulting in a read-only guest device keeping write
