For improved const-correctness.
This work was initially posted here:
https://lore.kernel.org/lkml/20250827192233.447920-1-max.kellermann@ionos.com/
.. but got rejected by Lorenzo Stoakes:

David Hildenbrand and Lorenzo Stoakes suggested splitting the patch
into smaller chunks. My second attempt with one smaller patch was met
with agreement:
https://lore.kernel.org/lkml/20250828130311.772993-1-max.kellermann@ionos.com/
Now this is the rest of the initial patch in small pieces, plus some
more.
Establishing const-correctness in this low-level part of the kernel
enables doing the same in higher-level parts, e.g. filesystems.
