Vlastimil Babka fa9b88e459 mm, slub: refactor free debug processing 
Since commit c7323a5ad0 ("mm/slub: restrict sysfs validation to debug
caches and make it safe"), caches with debugging enabled use the
free_debug_processing() function to do both freeing checks and actual
freeing to partial list under list_lock, bypassing the fast paths.

We will want to use the same path for CONFIG_SLUB_TINY, but without the
debugging checks, so refactor the code so that free_debug_processing()
does only the checks, while the freeing is handled by a new function
free_to_partial_list().

For consistency, change return parameter alloc_debug_processing() from
int to bool and correct the !SLUB_DEBUG variant to return true and not
false. This didn't matter until now, but will in the following changes.

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.
