Merge tag 'erofs-for-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs
Pull erofs updates from Gao Xiang:
"No outstanding new feature for this cycle.
Most of these commits are decompression cleanups which are part of the
ongoing development for subpage/folio compression support as well as
xattr cleanups for the upcoming xattr bloom filter optimization [1].
In addition, there are bugfixes to address some corner cases of
compressed images due to global data de-duplication and arm64 16k
pages.
Summary:
- Fix rare I/O hang on deduplicated compressed images due to loop
hooked chains
- Fix compact compression layout of 16k blocks on arm64 devices
- Fix atomic context detection of async decompression
- Decompression/Xattr code 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.
