Merge tag 'erofs-for-6.8-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs
Pull erofs updates from Gao Xiang:
"In this cycle, we'd like to enable basic sub-page compressed data
support for Android ecosystem (for vendors to try out 16k page size
with 4k-block images in their compatibility mode) as well as container
images (so that 4k-block images can be parsed on arm64 cloud servers
using 64k page size.)
In addition, there are several bugfixes and cleanups as usual. All
commits have been in -next for a while and no potential merge conflict
is observed.
Summary:
- Add basic sub-page compressed data support
- Fix a memory leak on MicroLZMA and DEFLATE compression
- Fix a rare LZ4 inplace decompression issue on recent x86 CPUs
- Fix a KASAN issue reported by syzbot around crafted images
- Some cleanups"

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.
