Hi Linus,
please pull the latest slab updates from:
git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab.git tags/slab-for-6.9
I'm not aware of any merge conflicts this time.
Thanks,
Vlastimil
======================================
- Freelist loading optimization (Chengming Zhou)
When the per-cpu slab is depleted and a new one loaded from the cpu partial
list, optimize the loading to avoid an irq enable/disable cycle. This results
in a 3.5% performance improvement on the "perf bench sched messaging" test.
- Kernel boot parameters cleanup after SLAB removal (Xiongwei Song)
Due to two different main slab implementations we've had boot parameters
prefixed either slab_ and slub_ with some later becoming an alias as both
implementations gained the same functionality (i.e. slab_nomerge vs
slub_nomerge). In order to eventually get rid of the implementation-specific
names, the canonical and documented parameters are now all prefixed slab_
and the slub_ variants become deprecated but still working aliases.
- SLAB_ kmem_cache creation flags cleanup (Vlastimil Babka)
The flags had hardcoded #define values which became tedious and error-prone
when adding new ones. Assign the values via an enum that takes care of
providing unique bit numbers. Also deprecate SLAB_MEM_SPREAD which was only
used by SLAB, so it's a no-op since SLAB removal. Assign it an explicit zero
value. The removals of the flag usage are handled independently in the
respective subsystems, with a final removal of any leftover usage planned
for the next release.
- Misc cleanups and fixes (Chengming Zhou, Xiaolei Wang, Zheng Yejian)
Includes removal of unused code or function parameters and a fix of a
memleak.
