Linus Torvalds 6e5a0c30b6 Scheduler changes for v6.10:
- Add cpufreq pressure feedback for the scheduler
 
  - Rework misfit load-balancing wrt. affinity restrictions
 
  - Clean up and simplify the code around ::overutilized and
    ::overload access.
 
  - Simplify sched_balance_newidle()
 
  - Bump SCHEDSTAT_VERSION to 16 due to a cleanup of CPU_MAX_IDLE_TYPES
    handling that changed the output.
 
  - Rework & clean up <asm/vtime.h> interactions wrt. arch_vtime_task_switch()
 
  - Reorganize, clean up and unify most of the higher level
    scheduler balancing function names around the sched_balance_*()
    prefix.
 
  - Simplify the balancing flag code (sched_balance_running)

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 reStructuredText 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.
