Here's the general order: - 1 week before Linus merge window: I stop putting new stuff into xxx-next. - Linus merge window open: I push stuff to Linus, new stuff stays in -pending. - Linus merge window close: I ff my -next trees to -rc1, merge stuff from -pending. In this case, your patch will go from pending-rebases to DaveM, not virtio-next. Which I will do now...
