   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).
