Quick question: this looks a lot like the "flexible array" mechanism which went in around a year ago, and which is documented in Documentation/flexible-arrays.txt. I'm not sure we need two of these... That said, it appears that there are still no users of flexible arrays. If your virtually-indexed arrays provide something that flexible arrays don't, perhaps your implementation should replace flexible arrays?
Thanks,
