Merge branch 'slab/for-6.4/slob-removal' into slab/for-next
A series by myself to remove CONFIG_SLOB:
The SLOB allocator was deprecated in 6.2 and there have been no
complaints so far so let's proceed with the removal.
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.
Otherwise it's all straightforward removal. After this series, 'git grep
slob' or 'git grep SLOB' will have 3 remaining relevant hits in non-mm
code:
- tomoyo - patch submitted and carried there, doesn't need to wait for
this series
- skbuff - patch to cleanup now-unnecessary #ifdefs will be posted to
netdev after this is merged, as requested to avoid conflicts
- ftrace ring_buffer - patch to remove obsolete comment is carried there
The rest of 'git grep SLOB' hits are false positives, or intentional
(CREDITS, and mm/Kconfig SLUB_TINY description to help those that will
happen to migrate later).
