Merge tag 'slab-for-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
"The main change is naturally the SLOB removal. Since its deprecation
in 6.2 I've seen no complaints so hopefully SLUB_(TINY) works well for
everyone and we can proceed.
Besides the code cleanup, the main immediate benefit will be allowing
kfree() family of function to work on kmem_cache_alloc() objects,
which was incompatible with SLOB. This includes kfree_rcu() which had
no kmem_cache_free_rcu() counterpart yet and now it shouldn't be
necessary anymore.
Besides that, there are several small code and comment improvements
from Thomas, Thorsten and Vernon"
* tag 'slab-for-6.4' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab:
mm/slab: document kfree() as allowed for kmem_cache_alloc() objects
mm/slob: remove slob.c
mm/slab: remove CONFIG_SLOB code from slab common code
mm, pagemap: remove SLOB and SLQB from comments and documentation
mm, page_flags: remove PG_slob_free
mm/slob: remove CONFIG_SLOB
mm/slub: fix help comment of SLUB_DEBUG
mm: slub: make kobj_type structure constant
slab: Adjust comment after refactoring of gfp.h
When using cull option with 'tg' flag, the fprintf is using pid instead
of tgid. It should use tgid instead.

With SLOB removed we no longer need the PG_slob_free alias for
PG_private. Also update tools/mm/page-types.

Right now there is no way to provide additional cflags/ldflags when
building tools/vm binaries. And using eg. make CFLAGS=<options> will
override the CFLAGS being set in the Makefile, making the build fail since
it requires the include of the ../lib dir (for libapi).
This change then allows you to specify:
CFLAGS=<options> LDFLAGS=<options> make V=1 -C tools/vm
And the options will be correctly appended as can be seen from the
make output.

Rename tools/vm to tools/mm for being more consistent with the code and
documentation directories, and won't be confused with virtual machines.
