hi,

I appreciate the effort, but I'm actually working on a series to
completely stop using page->index and page->lru . It works, only needs
reviews and some proper testing; I will send it out next week.

if David can send a polished version of his patch, I can pick it,
otherwise I'll polish the WIP he has already sent.

@David: can you please polish and resend your patch?

with that done, this whole series becomes moot (sorry)
