Currently we have multiple kmem_cache_create*() variants that take up to seven separate parameters with one of the functions having to grow an eigth parameter in the future to handle both usercopy and a custom freelist pointer. Add a struct kmem_cache_args structure and move less common parameters into it. Core parameters such as name, object size, and flags continue to be passed separately. Add a new function __kmem_cache_create_args() that takes a struct kmem_cache_args pointer and port do_kmem_cache_create_usercopy() over to it. In follow-up patches we will port the other kmem_cache_create*() variants over to it as well.

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 reStructuredText 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.
