Patch series "Convert huge_zero_page to huge_zero_folio". Almost all the callers of is_huge_zero_page() already have a folio. And they should -- is_huge_zero_page() will return false for tail pages, even if they're tail pages of the huge zero page. That's confusing, and one of the benefits of the folio conversion is to get rid of this confusion. This patch (of 8): There's no need to convert to a page, much less a folio. We can tell from the pmd whether it is a huge zero page or not. Saves 60 bytes of text.

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.
