Patch series "mm, swap: clean up swap cache mapping helper", v3. This series removes usage of folio_index usage in fs/, and remove swap cache checking in folio_contains. Currently, the swap cache is already no longer directly exposed to fs, and swap cache will be more different from page cache. Clean up the helpers first to simplify the code and eliminate the helpers used for resolving circular header dependency issue between filemap and swap headers, and prepare for further changes. This patch (of 6): folio_index is only needed for mixed usage of page cache and swap cache, for pure page cache usage, the caller can just use folio->index instead. It can't be a swap cache folio here. Swap mapping may only call into fs through `swap_rw` but fuse does not use that method for SWAP.

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.
