Linux kernel source tree

Mauro says: This series increases the minimal requirements for Sphinx and Python, and drop some backward-compatible code from Sphinx extension. Looking at Sphinx release dates: Release 2.4.0 (released Feb 09, 2020) Release 2.4.4 (released Mar 05, 2020) (current minimal requirement) Release 3.4.0 (released Dec 20, 2020) Release 3.4.3 (released Jan 08, 2021) (https://www.sphinx-doc.org/en/master/changes/index.html) And Python release dates, we have: Python Release date 3.5 2015-09-13 (current minimal requirement) 3.6 2016-12-23 3.7 2018-06-27 3.8 2019-10-14 3.9 2020-10-05 3.10 2021-10-04 (according with https://en.wikipedia.org/w/index.php?title=History_of_Python) The new minimal requirements are now compatible with the toolset available on Jan, 2021, e.g.: - Sphinx 3.4.3; - Python 3.9 The new Sphinx minimal requirement allows dropping all backward-compatible code we have at kernel-doc and at Sphinx extensions. The new Python minimal requirement also matches the current required level for almost all scripts (*). Those matches a 4-years old toolchain, which sounds a reasonable period of time, as Python/Sphinx aren't required for the Kernel build. (*) Except for a couple scripts inside tools that require python 3.10: $ vermin -v $(git ls-files '*.py')|grep 3.10 !2, 3.10 tools/net/sunrpc/xdrgen/generators/__init__.py !2, 3.10 tools/net/sunrpc/xdrgen/generators/program.py !2, 3.10 tools/net/sunrpc/xdrgen/subcmds/source.py !2, 3.10 tools/net/sunrpc/xdrgen/xdr_ast.py !2, 3.10 tools/perf/scripts/python/mem-phys-addr.py !2, 3.10 tools/power/cpupower/bindings/python/test_raw_pylibcpupower.py Such scripts aren't required for Kernel builds, so it should be OK to set minimal python version to 3.9. |

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.
