I think it would be fine if we run the batches according to the ftrace page groups. Which will be guaranteed to be sorted. I try to keep the groups to a minimum, thus it shouldn't be too many ipi busts. Although, my new work may actually make more page groups by trying to cut down on the dyn_ftrace size by using offsets. If a function extends outside the offset range, a new page group will need to be created. -- Steve
