[GIT PULL] slab updates for 6.16

Hi Linus,

please pull the latest slab updates from:

git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-6.16

AFAIK no conflicts. A small PR this time, but the next merge window should
be different. The second commit came somewhat late hence the PR is also
later than usual to allow for more -next soak time.

Thanks,
Vlastimil

======================================

* Make kvmalloc() more suitable for callers that need it to succeed, but
without unnecessary overhead by reclaim and compaction to get a physically
contiguous allocation. Instead fallback to vmalloc() more easily by default,
unless instructed by __GFP_RETRY_MAYFAIL to prefer kmalloc() harder.
This should allow the removal of a xfs-specific workaround (Michal Hocko)

* Remove potentially excessive warnings due to memory pressure when allocating
structures for per-object allocation profiling metadata (Usama Arif)
