They fix pageflip scheduling to always flip at the right target vblank and pageflip completion events to send out the correct vblank count and timestamp of flip completion.

Thanks for your extensive testing and the fixes. I'll let Andrey review this more thoroughly as he's spent quite a bit of time trying to get our flip/vblank model right. This series looks quite sensible to me, though, so feel free to add my
