I'd much prefer a wrapper around fsstress than have to code this
into every test. Something like:

run_fstress()
{
	args=""

	while [ $# -gt 0 ]; do
		case "$1" in
		-n) args="$args $1 $(($2 * $TIME_FACTOR))"; shift ;;
		-p) args="$args $1 $(($2 * $LOAD_FACTOR))"; shift ;;
		*) args="$args $1" ;;
		esac

		shift
	done

	$FSSTRESS_PROG $args
}

And so all you need to do is something like:

$ sed -i 's/\$FSSTRESS_PROG/run_fsstress/' [0-9][0-9][0-9]

To convert all tests that use fsstress to do this.

You might also want to do this for the tests that run dirstress as
well, and create a "stress" group so that you can run just
the stress tests easily....

Cheers,

Dave.
