This snippet is enclosed in the #else of an #ifdef _KERNEL, where the
entire #ifdef _KERNEL is not that long, so if you're looking at the
actual file rather than a diff, it's pretty clear.  And just a few lines
above the #ifdef _KERNEL is the comment:

 *                                                                                                 

 *      This code can be compiled stand-alone for
debugging.
