Merge tag 'slab-for-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab

Pull slab updates from Vlastimil Babka:

- SLOB deprecation and SLUB_TINY

The SLOB allocator adds maintenance burden and stands in the way of
API improvements [1]. Deprecate it by renaming the config option (to
make users notice) to CONFIG_SLOB_DEPRECATED with updated help text.
SLUB should be used instead as SLAB will be the next on the removal
list.

Based on reports from a riscv k210 board with 8MB RAM, add a
CONFIG_SLUB_TINY option to minimize SLUB's memory usage at the
expense of scalability. This has resolved the k210 regression [2] so
in case there are no others (that wouldn't be resolvable by further
tweaks to SLUB_TINY) plan is to remove SLOB in a few cycles.

Existing defconfigs with CONFIG_SLOB are converted to
CONFIG_SLUB_TINY.

- kmalloc() slub_debug redzone improvements

A series from Feng Tang that builds on the tracking or requested size
for kmalloc() allocations (for caches with debugging enabled) added
in 6.1, to make redzone checks consider the requested size and not
the rounded up one, in order to catch more subtle buffer overruns.
Includes new slub_kunit test.

- struct slab fields reordering to accomodate larger rcu_head

RCU folks would like to grow rcu_head with debugging options, which
breaks current struct slab layout's assumptions, so reorganize it to
make this possible.

- Miscellaneous improvements/fixes:
- __alloc_size checking compiler workaround (Kees Cook)
- Optimize and cleanup SLUB's sysfs init (Rasmus Villemoes)
- Make SLAB compatible with PROVE_RAW_LOCK_NESTING (Jiri Kosina)
- Correct SLUB's percpu allocation estimates (Baoquan He)
- Re-enableS LUB's run-time failslab sysfs control (Alexander Atanasov)
- Make tools/vm/slabinfo more user friendly when not run as root (Rong Tao)
- Dead code removal in SLUB (Hyeonggon Yoo)

Merge branch 'slub-tiny-v1r6' into slab/for-next

Merge my series [1] to deprecate the SLOB allocator.
- Renames CONFIG_SLOB to CONFIG_SLOB_DEPRECATED with deprecation notice.
- The recommended replacement is CONFIG_SLUB, optionally with the new
CONFIG_SLUB_TINY tweaks for systems with 16MB or less RAM.
- Use cases that stopped working with CONFIG_SLUB_TINY instead of SLOB
should be reported to linux-mm@kvack.org and slab maintainers,
otherwise SLOB will be removed in few cycles.

mm, slob: rename CONFIG_SLOB to CONFIG_SLOB_DEPRECATED

As explained in [1], we would like to remove SLOB if possible.

- There are no known users that need its somewhat lower memory footprint
so much that they cannot handle SLUB (after some modifications by the
previous patches) instead.

- It is an extra maintenance burden, and a number of features are
incompatible with it.

- It blocks the API improvement of allowing kfree() on objects allocated
via kmem_cache_alloc().

As the first step, rename the CONFIG_SLOB option in the slab allocator
configuration choice to CONFIG_SLOB_DEPRECATED. Add CONFIG_SLOB
depending on CONFIG_SLOB_DEPRECATED as an internal option to avoid code
churn. This will cause existing .config files and defconfigs with
CONFIG_SLOB=y to silently switch to the default (and recommended
replacement) SLUB, while still allowing SLOB to be configured by anyone
that notices and needs it. But those should contact the slab maintainers
and linux-mm@kvack.org as explained in the updated help. With no valid
objections, the plan is to update the existing defconfigs to SLUB and
remove SLOB in a few cycles.

To make SLUB more suitable replacement for SLOB, a CONFIG_SLUB_TINY
option was introduced to limit SLUB's memory overhead.
There is a number of defconfigs specifying CONFIG_SLOB=y. As part of
this patch, update them to select CONFIG_SLUB and CONFIG_SLUB_TINY.
