Subject: [PATCH 0/5] slab: preparatory cleanups before adding sheaves to
 all caches

These patches are separated from the RFC [1] since that needs more work
and 6.19 would be unrelistic for the whole series at this point. This
subset should be safe to land, improve the codebase on its own and make
the followup smaller.

Patch "slab: make __slab_free() more clear" is a new one based on review
of one of the RFC patches where __slab_free() was found rather tricky.
