Stephen,

please take a look at my VM patch at http://www.surriel.com/patches/
(either the -test4 or the -test7-pre4 one).

If you look closely at mm/vmscan.c::page_launder(), you'll see
that we should be able to add the flush callback with only about
5 to 10 lines of changed code ...

(and even more ... we just about *need* the flush callback when
we're running in a multi-queue VM)

regards,

Rik
