  19 # Description:
  20 # Trigger fio runs using the random_reads job file. The number of runs and
  21 # data collected is determined by the PERF_* variables. See do_fio_run for
  22 # details about these variables.
  23 #
  24 # The files to read from are created prior to the first fio run, and used
  25 # for all fio runs. The ARC is cleared with `zinject -a` prior to each run
  26 # so reads will go to disk.
