Linus Torvalds 7ab044a4f4 workqueue: Changes for v6.5 
* Concurrency-managed per-cpu work items that hog CPUs and delay the
   execution of other work items are now automatically detected and excluded
   from concurrency management. Reporting on such work items can also be
   enabled through a config option.
 
 * Added tools/workqueue/wq_monitor.py which improves visibility into
   workqueue usages and behaviors.
 
 * Includes Arnd's minimal fix for gcc-13 enum warning on 32bit compiles.
   This conflicts with afa4bb778e ("workqueue: clean up WORK_* constant
   types, clarify masking") in master. Can be resolved by picking the master
   version.

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.
