There is an query about fio_param in /benchs/fio_zone_writes.py(line57)

When I study the params of fio config in /benchs/fio_zone_writes.py, I find the fio I/O type is randwrite. Is this different from the description in README.md? As far as I know, ZNS SSDs only support sequential writing.

/benchs/fio_zone_writes.py:

        fio_param = ("--filename=%s"
                     " --io_size=%sk"
                     " --log_avg_msec=1000"
                     " --write_bw_log=%s/fio_zone_write"
                     " --output=%s/fio_zone_write.log"
                     " --direct=1 --zonemode=zbd"
                     " --name=seqwriter --rw=randwrite --norandommap"
                     " --bs=64k --max_open_zones=%s %s") % (dev,
                                                            io_size,
                                                            self.result_path(),
                                                            self.result_path(),
                                                            max_open_zones,
                                                            extra)

The describe about fio_zone_writes in README.md:

• executes a fio workload that writes sequential to 14 zones in parallel and while writing 6 times the capacity of the device.

Thanks!
