+; Using the libaio ioengine, random write to a (zoned) block device. Write
+; target zones are chosen randomly among the first 128 zones starting from
+; device offset corresponding to the 524th zone of the device (524 x 256 MB).
+; For first 3 seconds, run only random write. After that, run random write job
+; and garbage collection simulation job in parallel. The garbage collection
+; simulation job runs trim workload to reset the 128 zones randomly. Use flow
+; option to make the zone resets happen every 128 blocks writes by the other
+; job. This example does not specify max_open_zones. The limit of maximum
+; open zones is obtained from the target block device.
