Patch series "Start converting buffer_heads to use folios". I was hoping that filesystems would convert from buffer_heads to iomap, but that's not happening particularly quickly. So the buffer_head infrastructure needs to be converted from being page-based to being folio-based. This patch (of 12): Buffer heads point to the allocation (ie the folio), not the page. This is currently the same thing for all filesystems that use buffer heads, so this is a safe transitional step.

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.
