Stacking multiple arrays using bitmaps on top of each other is weird. But what if other block remappers starting to use this for other remapping and they are stacked? That seems much more likely unfotunately, so maybe we can't go down this route after all, sorry for leading you to it. So instead just write a comment documenting why you switch to a different stack using the workqueue.
