2385 *
2386 * In an ideal world we would unconditionally create a new BlockBackend for
2387 * qemuio_command(), but we have commands like 'reopen' and want them to
2388 * take effect on the exact BlockBackend whose name the user passed instead
2389 * of just on a temporary copy of it.
2390 *
2391 * Another problem is that deleting the temporary BlockBackend involves
2392 * draining all requests on it first, but some qemu-iotests cases want to
2393 * issue multiple aio_read/write requests and expect them to complete in
2394 * the background while the monitor has already returned.
2395 *
2396 * This is also what prevents us from saving the original permissions and
2397 * restoring them later: We can't revoke permissions until all requests
2398 * have completed, and we don't know when that is nor can we really let
2399 * anything else run before we have revoken them to avoid race conditions.
2400 *
2401 * What happens now is that command() in qemu-io-cmds.c can extend the
2402 * permissions if necessary for the qemu-io command. And they simply stay
2403 * extended, possibly resulting in a read-only guest device keeping write
2404 * permissions. Ugly, but it appears to be the lesser evil.
