folio_is_zone_device() is equivalent to is_zone_device_page(), folio_is_device_private() is equivalent to is_device_private_page(), and folio_is_pinnable() is equivalent to is_pinnable_page(). All of these tests return the same result for every page in the folio, so we can just pass the head page of the folio to the page variant of the function.

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.
