2547 *
2548 * In an ideal world we would unconditionally create a new BlockBackend for

2550 * take effect on the exact BlockBackend whose name the user passed instead
2551 * of just on a temporary copy of it.
2552 *
2553 * Another problem is that deleting the temporary BlockBackend involves
2554 * draining all requests on it first, but some qemu-iotests cases want to
2555 * issue multiple aio_read/write requests and expect them to complete in
2556 * the background while the monitor has already returned.
2557 *
2558 * This is also what prevents us from saving the original permissions and
2559 * restoring them later: We can't revoke permissions until all requests
2560 * have completed, and we don't know when that is nor can we really let
2561 * anything else run before we have revoken them to avoid race conditions.
2562 *
2563 * What happens now is that command() in qemu-io-cmds.c can extend the
2564 * permissions if necessary for the qemu-io command. And they simply stay
2565 * extended, possibly resulting in a read-only guest device keeping write
2566 * permissions. Ugly, but it appears to be the lesser evil.
