The 'type' of the function new_kmalloc_cache should be
enum kmalloc_cache_type instead of int, so correct it.

I think you mean type of the 'i' variable, not the type of
new_kmalloc_cache() function. Also the name of the patch is
misleading. How about
mm, slab_common: use enum kmalloc_cache_type to iterate over kmalloc caches ?
Or something like this.

The rest of the series looks good to me.

Please, feel free to use

for patches [1-3] in the series after fixing this commit message and
restoring __initconst.

Patch [4] needs some additional clarifications, IMO.

Thank you!

I will add more clarification in v3.
