This should result in better code. Currently kfree() makes a function call between compilation units to __kmem_cache_free() which does its own virt_to_slab(), throwing away the struct slab pointer we already had in kfree(). Now it can be reused. Additionally kfree() can now inline the whole SLUB freeing fastpath. Also move over free_large_kmalloc() as the only callsites are now in slub.c, and make it static.

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.
