Introduce folio_set_swap_entry() to abstract how both folio->private and swp_entry_t work. Use swap_address_space() directly instead of indirecting through folio_mapping(). Include an assertion that the old folio is not large as we only allocate a single-page folio to replace it. Use folio_put_refs() instead of calling folio_put() twice.

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.
