Pull erofs updates from Gao Xiang:
"In this cycle, large folios are now enabled in the iomap/fscache mode
for uncompressed files first. In order to do that, we've also cleaned
up better interfaces between erofs and fscache, which are acked by
fscache/netfs folks and included in this pull request.
Other than that, there are random fixes around erofs over fscache and
crafted images by syzbot, minor cleanups and documentation updates.
Summary:
- Enable large folios for iomap/fscache mode
- Avoid sysfs warning due to mounting twice with the same fsid and
domain_id in fscache mode
- Refine fscache interface among erofs, fscache, and cachefiles
- Use kmap_local_page() only for metabuf
- Fixes around crafted images found by syzbot
- Minor cleanups and documentation updates"

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.
