 * 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).

Remove sdt.h It's mostly a noop on ZoL and it conflicts with platforms that support dtrace. Remove this header to resolve the conflict.
