Hi all, This small set of patches fill in a couple of missing info and update outdated guidelines in doc-guide/sphinx.rst. Patch 1/5 adds a footnote on expected improvements of images embedded in PDF documents by the support of Inkscape in kfigure.py added in v5.18. Patch 2/5 mentions the make variable SPHINXDIRS, which is helpful in test-building a subset of documents. This change was inspired by an earlier comment of Maciej. He also suggested the update of changes.rst to indicate the requirement of Sphinx 2.4 or later for "make htmldocs", but changes.rst is not touched in this patch set as there is an on-going discussion about updating minimal required version of Sphinx [1]. [1]: "Sphinx pre v3 -- removing support" https://lore.kernel.org/linux-doc/LO3P123MB26810D190462B6BBBF1305F6C2A19@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/ Patches 3/5 and 4/5 are RFCs. The guidelines for title adornments were written well before the transition to subdirectory based documentation. Here, I'm suggesting a version of guidelines based on my personal preference. I am expecting at least a few comments from others because I don't think there is any consensus on how far these guidelines should be followed, especially for existing documents. This update was inspired by private communication with Miguel and Jon. Patch 3/5 updates the guidelines for title adornments. The change is done in-place for ease of review. Patch 4/5 moves the item expanded by Patch 3/5 from the bullet lists into its own subsection. Patch 5/5 is a PoC of adding a meta title to kernel-doc.rst by using the "title" directive mentioned in Patch 3/5. Any feedback is welcome!
