Matthew just told us that folios con't have subpages (https://lkml.kernel.org/r/ZxsRCyBSO-C27Uzn@xxxxxxxxxxxxxxxxxxxx). Please carefully describe the impact of this change. I think it's "small cleanup and optimization?" Also, I find the changelog rather hard to follow. I think we're adding the alignment operation to the callee and hence removing it from the caller?
