[PATCH v10 00/14] Don't generate netlink .rst files inside $(srctree)

[Mauro Carvalho Chehab <mchehab+huawei@kernel.org>]

Hi Jon,

That's the v10 version of the parser-yaml series, addressing a couple of
issues raised by Donald.

It should apply cleanly on the top of docs-next, as I just rebased on
the top of docs/docs-next.

Please merge it via your tree, as I have another patch series that will
depend on this one.

As discussed at:
   https://lore.kernel.org/all/20250610101331.62ba466f@foz.lan/

changeset f061c9f7d058 ("Documentation: Document each netlink family")
added a logic which generates *.rst files inside $(srctree). This is bad
when O=<BUILDDIR> is used.

A recent change renamed the yaml files used by Netlink, revealing a bad
side effect: as "make cleandocs" don't clean the produced files and symbols
appear duplicated for people that don't build the kernel from scratch.

This series adds an yaml parser extension and uses an index file with glob for
*. We opted to write such extension in a way that no actual yaml conversion
code is inside it. This makes it flexible enough to handle other types of yaml
files in the future. The actual yaml conversion logic were placed at 
netlink_yml_parser.py. 

As requested by YNL maintainers, this version has netlink_yml_parser.py
inside tools/net/ynl/pyynl/ directory. I don't like mixing libraries with
binaries, nor to have Python libraries spread all over the Kernel. IMO,
the best is to put all of them on a common place (scripts/lib, python/lib,
lib/python, ...) but, as this can be solved later, for now let's keep it this
way.

---

v10:
- added a R-B from Donald on patch 5;
- added an extra patch fixing issues with line numbers. I opted to
  make  it a separate patch, as this was not a trivial fix, and 
  I wanted to have it documented why the original way doesn't
  work, as this information can be useful in the future.

v9:
- did some cleanups due to changes caused by rebases;
- added some reviewed-by/reported-by/tested-by tags;
- addressed some pylint problems at the line numbering patch.

v8:
- minor fixes based on Donald's feedback;
- removed unrelated patches.

v7:
- Added a patch to cleanup conf.py and address coding style issues;
- Added a docutils version check logic to detect known issues when
  building the docs with too old or too new docutils version.  The
  actuall min/max vesion depends on Sphinx version.

v6:
- YNL doc parser is now at tools/net/ynl/pyynl/lib/doc_generator.py;
- two patches got merged;
- added instructions to test docs with Sphinx 3.4.3 (minimal supported
  version);
- minor fixes.

v5:
- some patch reorg;
- netlink_yml_parser.py is now together with ynl tools;
- minor fixes.

v4:
- Renamed the YNL parser class;
- some minor patch cleanups and merges;
- added an extra patch to fix a insert_pattern/exclude_pattern logic when
   SPHINXDIRS is used.

v3:
- Two series got merged altogether:
  - https://lore.kernel.org/linux-doc/cover.1749723671.git.mchehab+huawei@kernel.org/T/#t
  - https://lore.kernel.org/linux-doc/cover.1749735022.git.mchehab+huawei@kernel.org

- Added an extra patch to update MAINTAINERS to point to YNL library
- Added a (somewhat unrelated) patch that remove warnings check when
  running "make cleandocs".
