 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).
