For a random write pattern to a zoned block device, fio requires --direct=1 and --zonemode=zbd options as well as deadline I/O scheduler to be specified. Specify these options and set the I/O scheduler if the target device is a zoned block device. Before doing that, also make sure that the deadline scheduler is available and that fio supports the zbd zone mode. Set CAN_BE_ZONED flag to run this test case for zoned block devices.
