Pull documentation updates from Jonathan Corbet: "This has been another busy cycle for documentation, with a lot of build-system thrashing. That work should slow down from here on out. - The various scripts and tools for documentation were spread out in several directories; now they are (almost) all coalesced under tools/docs/. The holdout is the kernel-doc script, which cannot be easily moved without some further thought. - As the amount of Python code increases, we are accumulating modules that are imported by multiple programs. These modules have been pulled together under tools/lib/python/ -- at least, for documentation-related programs. There is other Python code in the tree that might eventually want to move toward this organization. - The Perl kernel-doc.pl script has been removed. It is no longer used by default, and nobody has missed it, least of all anybody who actually had to look at it. - The docs build was controlled by a complex mess of makefilese that few dared to touch. Mauro has moved that logic into a new program (tools/docs/sphinx-build-wrapper) that, with any luck at all, will be far easier to understand and maintain. - The get_feat.pl program, used to access information under Documentation/features/, has been rewritten in Python, bringing an end to the use of Perl in the docs subsystem. - The top-level README file has been reorganized into a more reader-friendly presentation. - A lot of Chinese translation additions - Typo fixes and documentation updates as usual" * tag 'docs-6.19' of git://git.lwn.net/linux: (164 commits) docs: makefile: move rustdoc check to the build wrapper README: restructure with role-based documentation and guidelines docs: kdoc: various fixes for grammar, spelling, punctuation docs: kdoc_parser: use '@' for Excess enum value docs: submitting-patches: Clarify that removal of Acks needs explanation too docs: kdoc_parser: add data/function attributes to ignore docs: MAINTAINERS: update Mauro's files/paths docs/zh_CN: Add wd719x.rst translation docs/zh_CN: Add libsas.rst translation get_feat.pl: remove it, as it got replaced by get_feat.py Documentation/sphinx/kernel_feat.py: use class directly tools/docs/get_feat.py: convert get_feat.pl to Python Documentation/admin-guide: fix typo and comment in cscope example docs/zh_CN: Add data-integrity.rst translation docs/zh_CN: Add blk-mq.rst translation docs/zh_CN: Add block/index.rst translation docs/zh_CN: Update the Chinese translation of kbuild.rst docs: bring some order to our Python module hierarchy docs: Move the python libraries to tools/lib/python Documentation/kernel-parameters: Move the kernel build options ...
