  20   20  # Trigger fio runs using the sequential_writes job file. The number of runs and
  21   21  # data collected is determined by the PERF_* variables. See do_fio_run for
  22   22  # details about these variables.
  23   23  #
  24   24  # Prior to each fio run the dataset is recreated, and fio writes new files
  25   25  # into an otherwise empty pool.
