410 * The set-error SDT probe is extra static, in that we declare its fake
411 * function literally, rather than with the DTRACE_PROBE1() macro. This is
412 * necessary so that SET_ERROR() can evaluate to a value, which wouldn't
413 * be possible if it required multiple statements (to declare the function
414 * and then call it).
415 *
416 * SET_ERROR() uses the comma operator so that it can be used without much
417 * additional code. For example, "return (EINVAL);" becomes
418 * "return (SET_ERROR(EINVAL));". Note that the argument will be evaluated
419 * twice, so it should not have side effects (e.g. something like:
420 * "return (SET_ERROR(log_error(EINVAL, info)));" would log the error twice).
