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