Linus Torvalds cba2348ab1 Merge tag 'xfs-fixes-7.3-rc3' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs fixes from Carlos Maiolino:
 "More than the usual amount of fixes.

  The highlights here are a block under reservation fix which caused an
  assert to be triggered in non-default configurations. The assert,
  initially added on 7.3-rc2 just makes the problem explicit but is not
  the cause. Another highlight is a missed lock/unlock mutex in the xfs
  healthmonitor which was causing lockdeps warnings.

  Besides those two, this also contains a myriad of fixes for random
  bugs found by LLM tools in the healthmon, scrub and online repair.

  A few bug fixes for zoned xfs are also included.

  This also includes an accounting fix for our buffer slab cache where
  the memory payload associated to each object was not being properly
  accounted for.

  The remaining of the patches are a few lock context annotations added
  and/or fixed. They are mostly disabled by now, but still worth fixing
  before we get them enabled.

  And last but not least, a few clean ups"

Linux kernel
============

The Linux kernel is the core of any Linux operating system. It manages hardware,
system resources, and provides the fundamental services for all other software.

Quick Start
-----------

* Report a bug: See Documentation/admin-guide/reporting-issues.rst
* Get the latest kernel: https://kernel.org
* Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst
* Join the community: https://lore.kernel.org/

Essential Documentation
-----------------------

All users should be familiar with:

* Building requirements: Documentation/process/changes.rst
* Code of Conduct: Documentation/process/code-of-conduct.rst
* License: See COPYING

Documentation can be built with make htmldocs or viewed online at:
https://www.kernel.org/doc/html/latest/
