2471 *
2472 * In an ideal world we would unconditionally create a new BlockBackend for
2473 * qemuio_command(), but we have commands like 'reopen' and want them to
2474 * take effect on the exact BlockBackend whose name the user passed instead
2475 * of just on a temporary copy of it.
2476 *
2477 * Another problem is that deleting the temporary BlockBackend involves
2478 * draining all requests on it first, but some qemu-iotests cases want to
2479 * issue multiple aio_read/write requests and expect them to complete in
2480 * the background while the monitor has already returned.
2481 *
2482 * This is also what prevents us from saving the original permissions and
2483 * restoring them later: We can't revoke permissions until all requests
2484 * have completed, and we don't know when that is nor can we really let
2485 * anything else run before we have revoken them to avoid race conditions.
2486 *
2487 * What happens now is that command() in qemu-io-cmds.c can extend the
2488 * permissions if necessary for the qemu-io command. And they simply stay
2489 * extended, possibly resulting in a read-only guest device keeping write
2490 * permissions. Ugly, but it appears to be the lesser evil.
