; Using the psync ioengine, random write to a (zoned) block device. Write
; target zones are chosen randomly among the first 8 zones starting from device
; offset corresponding to the 524th zone of the device (524 x 256 MB). Simulate
; garbage collection operation using zone_reset_threshold and
; zone_reset_frequency options. The zone resets happen when total written data
; bytes is beyond 70% of 8 zones, and 8 = 1 / 0.125 blocks are written. This
; example does not specify max_open_zones. The limit of maximum open zones is
; obtained from the target block device.
