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