Vlastimil Babka ed4cdfbeb8 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).

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
