For now extent_buffer::pages[] are still only accepting single page pointer, thus we can migrate to folios pretty easily. As for single page, page and folio are 1:1 mapped, including their page flags. This patch would just do the conversion from struct page to struct folio, providing the first step to higher order folio in the future. This conversion is pretty simple: - extent_buffer::pages[] -> extent_buffer::folios[] - page_address(eb->pages[i]) -> folio_address(eb->pages[i]) - eb->pages[i] -> folio_page(eb->folios[i], 0) There would be more specific cleanups preparing for the incoming higher order folio support.

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.
