2422 *
2423 * In an ideal world we would unconditionally create a new BlockBackend for
2424 * qemuio_command(), but we have commands like 'reopen' and want them to
2425 * take effect on the exact BlockBackend whose name the user passed instead
2426 * of just on a temporary copy of it.
2427 *
2428 * Another problem is that deleting the temporary BlockBackend involves
2429 * draining all requests on it first, but some qemu-iotests cases want to
2430 * issue multiple aio_read/write requests and expect them to complete in
2431 * the background while the monitor has already returned.
2432 *
2433 * This is also what prevents us from saving the original permissions and
2434 * restoring them later: We can't revoke permissions until all requests
2435 * have completed, and we don't know when that is nor can we really let
2436 * anything else run before we have revoken them to avoid race conditions.
2437 *
2438 * What happens now is that command() in qemu-io-cmds.c can extend the
2439 * permissions if necessary for the qemu-io command. And they simply stay
2440 * extended, possibly resulting in a read-only guest device keeping write
2441 * permissions. Ugly, but it appears to be the lesser evil.
