Add a section with a few rules of thumb about how
quickly developers should address regressions to
Documentation/process/handling-regressions.rst; additionally,
add a short paragraph about this to the companion document
Documentation/admin-guide/reporting-regressions.rst as well.
The rules of thumb were written after studying the quotes from Linus
found in handling-regressions.rst and especially influenced by
statements like "Users are literally the _only_ thing that matters" and
"without users, your program is not a program, it's a pointless piece of
code that you might as well throw away". The author interpreted those in
perspective to how the various Linux kernel series are maintained
currently and what those practices might mean for users running into a
regression on a small or big kernel update.
That for example lead to the paragraph starting with "Aim to get fixes
for regressions mainlined within one week after identifying the culprit,
if the regression was introduced in a stable/longterm release or the
devel cycle for the latest mainline release". Some might see this as
pretty high bar, but on the other hand something like that is needed to
not leave users out in the cold for too long -- which can quickly happen
when updating to the latest stable series, as the previous one is
normally stamped "End of Life" about three or four weeks after a new
mainline release. This makes a lot of users switch during this
timeframe. Any of them thus risk running into regressions not promptly
fixed; even worse, once the previous stable series is EOLed for real,
users that face a regression might be left with only three options:
(1) continue running an outdated and thus potentially insecure kernel
version from an abandoned stable series
(2) run the kernel with the regression
(3) downgrade to an earlier longterm series still supported
This is better avoided, as (1) puts users and their data in danger, (2)
will only be possible if it's a minor regression that doesn't interfere
with booting or serious usage, and (3) might be regression itself or
impossible on the particular machine, as the users might require drivers
or features only introduced after the latest longterm series branched
of.
In the end this lead to the aforementioned "Aim to fix regression within
one week" part. It's also the reason for the "Try to resolve any
regressions introduced in the current development cycle before its
end.".

Quote from Jon's remark [1]:
I do notice that Documentation/conf.py is getting large and
unapproachable. At some future point, it might be nice to pull
all of the latex stuff out into a separate file where it won't
scare people who stumble into it by accident.
Pull LaTeX preamble settings added since commit 3b4c963243b1 ("docs:
conf.py: adjust the LaTeX document output") out into
sphinx/kerneldoc-preamble.sty.
It will be copied to the build directory by the added
"latex_additional_files" setting in conf.py.
As a bonus, LaTeX/TeX code can be maintained without escaping backslashes.
To compensate the loss of change history in sphinx/kerneldoc-preamble.sty,
here is a list of changes made in conf.py:
- f7ebe6b76940 ("docs: Activate exCJK only in CJK chapters")

, which is unhelpful.

4. The "format of comments" comment block
As suggested by Jani Nikula in a reply to my first version of this

information hub for comment formatting. The section DESCRIPTION already
points there, so the original comment block can just be removed.

The NAME section provides the doc title, while SYNOPSIS contains
the basic syntax and usage description, which will be printed
in the help document and in the error output produced on wrong script
usage.
The rationale is to give users simple and succinct enlightment,
at the same time structuring the script internally for the maintainers.
In the synopsis, Rst-only options are grouped around rst, and the rest is
arranged as in the OPTIONS subsections (yet to be translated into POD,
check at the end of the series).

Akira says:
This series resolves issues listed below:
1. Some of chapter and section counts in Table of Contents (TOC) in
large PDF docs collide with chapter/section titles, e.g., Chapters 10,
11, 12, and 13 and Section 10.10 in userspace-api.pdf.
2. In docs of more than 99 pages, page counts in TOC are not aligned
properly when maxdepth >= 2 is specified in toctree, e.g., Chapters 10,
12, and 13 in userspace-api.pdf
3. In TOC of Latin-script docs, quotation and apostrophe symbols look too
wide, e.g., Section 2.2 in userspace-api.pdf.
4. In TOC of translations, Korean chapter titles lose inter-phrase spaces.
5. On systems without "Noto Sans CJK" fonts, CJK chapters in translations
results in full of "TOFU" boxes, with a long build time and a large
log file containing lots of missing-font warnings.
6. In translations.pdf built by "make pdfdocs", ascii-art diagrams in CJK
are not aligned properly.
As LaTeX macros for CJK font settings can have Latin-script font
settings as well, settings under Documentation/translations/ can
be moved to the main conf.py.
By this change, translations.pdf built by top-level "make pdfdocs"
can have properly aligned ascii-art diagrams except for Korean
ones.
For the reason of remaining misalignment in Korean diagrams, see
changelog of commit a90dad8f610a ("docs: pdfdocs: Add conf.py
local to translations for ascii-art alignment").

On systems without "Noto Sans CJK" fonts, CJK chapters in
translations.pdf are full of "TOFU" boxes, with a long build time and
a large log file containing lots of missing-font warnings.
Avoid such waste of time and resources by skipping CJK chapters when
CJK fonts are not available.
To skip whole chapters, change the definition of
\kerneldocBegin{SC|TC|KR|JP} commands so that they can have an argument
to be ignored.
This works as far as the argument (#1) is not used in the command.
In place of skipped contents, put a note on skipped contents at the
beginning of the PDF.
Change the call sites in index.rst of CJK translations accordingly.
When CJK fonts are available, existing command definitions with
no argument just work. LaTeX engine will see additional pairs of
"{" and "}", which add a level of grouping without having any effect
on typesetting.

Korean (Hangul) titles in Table of Contents of translations.pdf
don't have inter-phrase spaces.
This is because the CJKspace option of xeCJK is disabled by
default.
Restore the spaces by enabling the option at the beginning of every
document and disable it in the \kerneldocBegin{SC|TC|JP} commands.

xeCJK is enabled in Table of Contents (TOC) so that translations.pdf
built by top-level "make pdfdocs" can have its TOC typeset properly.
This causes quotation marks and apostrophe symbols appear too wide in
Latin-script docs.
This is because (1) Sphinx converts ASCII symbols into multi-byte
UTF-8 ones in LaTeX and (2) in the SC variant of "Noto CJK" font
families, those UTF-8 symbols have full-width glyph.
The KR variant of the font families has half-width glyph for those
symbols and TOC pages should look nicer when it is used instead.
Switch the default CJK font families to the KR variant and teach
xeCJK of those symbols' widths.
To compensate the switch, teach xeCJK of the width in the SC and
TC variants.

Sphinx has its own set of width parameters of Table of Contents (TOC)
for LaTeX defined in its class definition of sphinxmanual.cls.
It also inherits parameters for chapter entries from report.cls of
original LaTeX base.
However, they are optimized assuming small documents with tens of
pages and chapters/sections of less than 10.
To cope with some of kernel-doc documents with more than 1000
pages and several tens of chapters/sections, definitions of those
parameters need to be adjusted.
Unfortunately, those parameters are hard coded in the class
definitions and need low-level LaTeX coding tricks to redefine.
As Sphinx 1.7.9 does not have \sphinxtableofcontentshook,
which defines those parameters in later Sphinx versions,
for compatibility with both pre-1.8 and later Sphinx versions,
empty the hook altogether and redefine \@pnumwidth, \l@chapter,
\l@section, and \@subsection commands originally defined in
report.cls.
Summary of parameter changes:
Width of page number (\@pnumwidth): 1.55em -> 2.7em
Width of chapter number: 1.5em -> 1.8em
Indent of section number: 1.5em -> 1.8em
Width of section number: 2.6em -> 3.2em
Indent of subsection number: 4.1em -> 5em
Width of subsection number: 3.5em -> 4.3em
Notes:
1. Parameters for subsection become relevant only when
":maxdepth: 3" is specified under "toctree::" (e.g., RCU/index.rst).
They can hold subsection numbers up to 5 digits such as "18.7.13"
(in RCU.pdf).
2. Number of chapters in driver-api.pdf is getting closer to 100.
When it reaches 100, another set of tweaks will be necessary.
3. The low-level LaTeX trick is mentioned in "Unofficial LaTeX2e
reference manual" at:
