Some functions are now unused; remove them. Make __mod_lruvec_page_state() unused and then remove it. Based on next-20231222. Boot tested only (as next-20231222 has some infelicities with regard to my testing setup) v2: Redo the slub conversion. Avoid using folio_alloc(), but do cast the struct page pointer that we get back from alloc_pages() to a folio pointer. Since we know it's a head page, this all works marvellously, and will continue to work until we can actually split folios, slabs and pages apart, at which time it will have to be redone. I tried a few different ways to make slab ignorant of folios and it's quite hard to do right now. Look for a patch series to make that possible soon. I wasn't expecting the previous version to make the next merge window, but since Andrew decided he wanted it, here's what I'm currently thinking ...
