This radix tree tag was planned to be reserved for other use in order to differ it from the current fixed-sized output compression management structure. I agree that it can be simplified for now, so I will test this series and apply. However, I think such XArray tagged pointer usage is useful. p.s. I'm converting this radix tree to XArray and cleaning up related functions for the next cycle as well.
