I know. But Greg hasn't merged that patch to the Linus' tree and instead
dropped it for unknown reason.
that's odd. I'll re-queue it for next -rc then. Thanks for the note.
Ok, it was dropped because the map/unmap buffer patch was dropped and
this was depending on that patch. Here's the updated patch. I'll send it
in a jiffy.
