With this flag is set, the server tells the client that it can send another option if the server got a request with an option it doesn't understand (instead of the server closing the connection.) Thus, the while(1) loop in 2/3. The kernel in Documentation/blockdev/nbd.txt points to the NBD project for documentation. The proto documentation is in [1]. Shouldn't Qemu also do the same ?
