    Timer measuring library.

    The test is supposed to define sampling function and set it in the tst_test
    structure the rest of the work is then done by the library.

    int sample(int clk_id, long long usec)
    {
	// Any setup done here

	tst_timer_start(clk_id);
	// Call that is being measured sleeps for usec
	tst_timer_stop();
	tst_timer_sample();

	// Any cleanup done here

	// Non-zero return exits the test
    }

    struct tst_test test = {
	.scall = "syscall_name()",
	.sample = sample,
    };
