 [https://developer.wordpress.org/reference/classes/wp_object_cache/flush/
 WP_Object_Cache::flush()] always returns true.

 [https://developer.wordpress.org/reference/functions/wp_cache_flush/
 wp_cache_flush()]  returns the value of calling
 `WP_Object_Cache::flush()`.  But, the DocBlock of `wp_cache_flush()` lists
 the return as:

 > True on success, false on failure.

 Is this discrepancy just a mistake, or is it because of the possibility of
 an object caching plugin returning something different?
