Merge branch 'slab/for-7.3/kfree_rcu_nolock' into slab/for-next
Merge series "mm/slab: introduce kfree_rcu_nolock() and improve
slub_kunit coverage" from Harry Yoo. From the cover letter [1]:
This series improves kmalloc_nolock() and kfree_nolock() coverage in
slub_kunit and introduces kfree_rcu_nolock() for unknown context as
suggested by Alexei Starovoitov.
Unknown context means the caller does not know whether spinning on a
lock is safe (e.g., a BPF program attached to an arbitrary kernel
function or in NMI context).
The slab allocator already supports unknown context via kmalloc_nolock()
and kfree_nolock(), but te slab allocator does not support freeing
objects by RCU in unknown context.
It is not ideal to have completely separate batching for unknown context
because the worst scenario where spinning on a lock would lead to

Merge branch 'slab/for-7.3/objext_split' into slab/for-next
Merge series "mm/slab, alloc_tag: reduce obj_ext memory waste" from
myself. From the cover letter [1]:
It's been bothering me that the memory usage of struct slabobj_ext
depend only on config options and not whether the fields are actually
used. So with both CONFIG_MEMCG=y and CONFIG_MEM_ALLOC_PROFILING=y there
is always objcg field and codetag_ref field. And thus:
1) Having memory allocation profiling config-enabled but not
boot-enabled means wasted memory on unused codetag_refs. This makes
it less suitable for a general distro config and the page allocator
side doesn't suffer from this, only slab and percpu.
2) Complementary, with memory allocation profiling enabled, there are
caches/slabs that don't need the objcg field, so memory is wasted on
those.

"Make boot time huge page allocation work nicely with kexec handover.
Today allocation of gigantic pages in HugeTLB cannot work reliably
with kexec handover (KHO):
- HugeTLB allocates gigantic pages using memblock and autoscaling of
KHO scratch accounts for these allocations. When gigantic pages
occupy half of the memory of more, KHO fails to allocate its
scratch memory.
- After kexec handover, memblock allocations exclusively use KHO
scratch that is not supposed to contain preserved memory. This
essentially blocks preservation of HugeTLB with gigantic pages.
