2576 *
2577 * In an ideal world we would unconditionally create a new BlockBackend for
2578 * qemuio_command(), but we have commands like 'reopen' and want them to
2579 * take effect on the exact BlockBackend whose name the user passed instead
2580 * of just on a temporary copy of it.
2581 *
2582 * Another problem is that deleting the temporary BlockBackend involves
2583 * draining all requests on it first, but some qemu-iotests cases want to
2584 * issue multiple aio_read/write requests and expect them to complete in
2585 * the background while the monitor has already returned.
2586 *
2587 * This is also what prevents us from saving the original permissions and
2588 * restoring them later: We can't revoke permissions until all requests
2589 * have completed, and we don't know when that is nor can we really let
2590 * anything else run before we have revoken them to avoid race conditions.
2591 *
2592 * What happens now is that command() in qemu-io-cmds.c can extend the
2593 * permissions if necessary for the qemu-io command. And they simply stay
2594 * extended, possibly resulting in a read-only guest device keeping write
2595 * permissions. Ugly, but it appears to be the lesser evil.
