  20 # Trigger fio runs using the sequential_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 not cleared to ensure that all data is cached.
