Linus Torvalds edaa5ddf38 Scheduler changes for v5.10:
- Reorganize & clean up the SD* flags definitions and add a bunch
    of sanity checks. These new checks caught quite a few bugs or at
    least inconsistencies, resulting in another set of patches.
 
  - Rseq updates, add MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ
 
  - Add a new tracepoint to improve CPU capacity tracking
 
  - Improve overloaded SMP system load-balancing behavior
 
  - Tweak SMT balancing
 
  - Energy-aware scheduling updates
 
  - NUMA balancing improvements
 
  - Deadline scheduler fixes and improvements
 
  - CPU isolation fixes
 
  - Misc cleanups, simplifications and smaller optimizations.

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.
