As discussed at:
	https://lore.kernel.org/linux-doc/871r9k6rmy.fsf@meer.lwn.net/

It is better to avoid using :doc:`foo` to refer to Documentation/foo.rst, as the
automarkup.py extension should handle it automatically, on most cases.

There are a couple of exceptions to this rule:

1. when :doc:  tag is used to point to a kernel-doc DOC: markup;
2. when it is used with a named tag, e. g. :doc:`some name <foo>`;

It should also be noticed that automarkup.py has currently an issue:
if one use a markup like:

	Documentation/dev-tools/kunit/api/test.rst
	  - documents all of the standard testing API excluding mocking
	    or mocking related features.

or, even:

	Documentation/dev-tools/kunit/api/test.rst
	    documents all of the standard testing API excluding mocking
	    or mocking related features.
	
The automarkup.py will simply ignore it. Not sure why. This patch series
avoid the above patterns (which is present only on 4 files), but it would be
nice to have a followup patch fixing the issue at automarkup.py.

On this series:

Patch 1 manually adjust the references inside driver-api/pm/devices.rst,
as there it uses :file:`foo` to refer to some Documentation/ files;

Patch 2 converts a table at Documentation/dev-tools/kunit/api/index.rst
into a list, carefully avoiding the 

Patch 3 converts the cross-references at the media documentation, also
avoiding the automarkup.py bug;

Patches 4-34 convert the other occurrences via a replace script. They were
manually edited, in order to honour 80-columns where possible.

I did a diff between the Sphinx 2.4.4 output before and after this patch
series in order to double-check that all converted Documentation/ 
references will produce <a href=<foo>.rst>foo title</a> tags.

This is much better, thanks! Do note that there's a merge conflict
(and another :doc:`` tag which needs updating) in the kunit-fixes
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest.git/commit/?h=kunit-fixes&id=11dbc62a73a7da9f3697e8ce83d07503c11dcabb

Okay, I went in deeper to understand the issue and indeed it wasn't what I
thought. The reason definitions are ignored by automarkup.py is because the main
loop iterates only over nodes that are of type paragraph:

    for para in doctree.traverse(nodes.paragraph):
        for node in para.traverse(nodes.Text):
            if not isinstance(node.parent, nodes.literal):
                node.parent.replace(node, markup_refs(name, app, node))

And inspecting the HTML output from your example, the definition name is inside
a <dt> tag, and it doesn't have a <p> inside. So in summary, automarkup.py will
only work on elements which are inside a <p> in the output.

Only applying the automarkup inside paragraphs seems like a good decision (which
covers text in lists and tables as well), so unless there are other types of
elements without paragraphs where automarkup should work, I think we should just
avoid using definition lists pointing to documents like that.

Yes, that's what I meant. 

Ok, that makes sense. Although after automarkup.py starts printing warnings on
missing references to files (which is a patch I still need to resend), it would
work out-of-the-box with relative paths. automarkup wouldn't face that false
positives issue since it ignores literal blocks, which isn't as easy for a
standalone script. But that's still in the future, we can discuss what to do
then after it is implemented, so full paths seem better for now.

Thanks,
Nícolas

Yeah, that's what I was suspecting, based on the comments.

Maybe something similar to the above could be done also for some
non-paragraph data. By looking at:

	https://docutils.sourceforge.io/docs/ref/doctree.html

It says that the body elements are:

	admonition, attention, block_quote, bullet_list, caution, citation, 
	comment, compound, container, danger, definition_list, doctest_block, 
	enumerated_list, error, field_list, figure, footnote, hint, image, 
	important, line_block, literal_block, note, option_list, paragraph, 
	pending, raw, rubric, substitution_definition, system_message, 
	table, target, tip, warning

So, perhaps a similar loop for definition_list would do the trick,
but maybe automarkup should also look at other types, like enum lists,
notes (and their variants, like error/warning) and footnotes.

No idea how this would affect the docs build time, though.

Checking the code or doing some tests are needed for us to be sure about what
of the above types docutils don't consider a paragraph.
