struct page_pool is rather performance critical and we use 16B of the first cache line to store 2 pointers used only by test code. Future patches will add more informational (non-fast path) attributes. It's convenient for the user of the API to not have to worry which fields are fast and which are slow path. Use struct groups to split the params into the two categories internally.

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.
