+/** @name       Deprecated VBGL shared folder helpers.
+ *
+ * @deprecated  These are all use the slow VbglR0HGCMCall interface, that
+ *              basically treat ring-0 and user land callers much the same.
+ *              Since 6.0 there is VbglR0HGCMFastCall() that does not bother with
+ *              repacking the request and locking/duplicating parameter buffers,
+ *              but just passes it along to the host and handles the waiting.
+ *              Also new in 6.0 is embedded buffers which saves a bit time on
+ *              guest and host by embedding parameter buffers into the request.
+ *
