Linus Torvalds 5c7ecada25 f2fs update for 6.4-rc1
In this round, we've mainly modified to support non-power-of-two zone size,
 which is not required for f2fs by design. In order to avoid arch dependency,
 we refactored the messy rb_entry structure shared across different extent_cache.
 In addition to the improvement, we've also fixed several subtle bugs and
 error cases.
 
 Enhancement:
 - support non-power-of-two zone size for zoned device
 - remove sharing the rb_entry structure in extent cache
 - refactor f2fs_gc to call checkpoint in urgent condition
 - support iopoll
 
 Bug fix:
 - fix potential corruption when moving a directory
 - fix to avoid use-after-free for cached IPU bio
 - fix the folio private usage
 - avoid kernel warnings or panics in the cp_error case
 - fix to recover quota data correctly
 - fix some bugs in atomic operations
 - fix system crash due to lack of free space in LFS
 - fix null pointer panic in tracepoint in __replace_atomic_write_block
 - fix iostat lock protection
 - fix scheduling while atomic in decompression path
 - preserve direct write semantics when buffering is forced
 - fix to call f2fs_wait_on_page_writeback() in f2fs_write_raw_pages()

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.
