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.
