2455 *
2456 * In an ideal world we would unconditionally create a new BlockBackend for
2457 * qemuio_command(), but we have commands like 'reopen' and want them to
2458 * take effect on the exact BlockBackend whose name the user passed instead
2459 * of just on a temporary copy of it.
2460 *
2461 * Another problem is that deleting the temporary BlockBackend involves
2462 * draining all requests on it first, but some qemu-iotests cases want to
2463 * issue multiple aio_read/write requests and expect them to complete in
2464 * the background while the monitor has already returned.
2465 *
2466 * This is also what prevents us from saving the original permissions and
2467 * restoring them later: We can't revoke permissions until all requests
2468 * have completed, and we don't know when that is nor can we really let
2469 * anything else run before we have revoken them to avoid race conditions.
2470 *
2471 * What happens now is that command() in qemu-io-cmds.c can extend the
2472 * permissions if necessary for the qemu-io command. And they simply stay
2473 * extended, possibly resulting in a read-only guest device keeping write
2474 * permissions. Ugly, but it appears to be the lesser evil.
