David Hildenbrand 07e09c483c mm/huge_memory: work on folio->swap instead of page->private when splitting folio
Let's work on folio->swap instead.  While at it, use folio_test_anon() and
folio_test_swapcache() -- the original folio remains valid even after
splitting (but is then an order-0 folio).

We can probably convert a lot more to folios in that code, let's focus on
folio->swap handling only for now.

README

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.
