Yes, I'm inclined to agree. Or at least not disagree. I'm more arguing that the order itself may not be the most interesting thing, and that I don't think the balancing has to take the order of the allocation into account - because it should be equivalent to just tell that it's a soft allocation (whether though the current !__GFP_HIGH or through a new __GFP_SOFT with slightly different logic).
