Hi, I've pushed another update branch slab-struct_slab-v4r1, and also to
-next. I've shortened git commit log lines to make checkpatch happier,
so no range-diff as it would be too long. I believe it would be useless
spam to post the whole series now, shortly before xmas, so I will do it
at rc8 time, to hopefully collect remaining reviews. But if anyone wants
a mailed version, I can do that.

Changes in v4:
- rebase to 5.16-rc6 to avoid a conflict with mainline
- collect acks/reviews/tested-by from Johannes, Roman, Hyeonggon Yoo -
thanks!
- in patch "mm/slub: Convert detached_freelist to use a struct slab"
renamed free_nonslab_page() to free_large_kmalloc() and use folio there,
as suggested by Roman
- in "mm/memcg: Convert slab objcgs from struct page to struct slab"
change one caller of slab_objcgs_check() to slab_objcgs() as suggested
by Johannes, realize the other caller should be also changed, and remove
slab_objcgs_check() completely.
