Let the user specify file patterns where to look for the EXPORT_SYMBOLs
in addition to the file with kernel-doc comments. This is directly based
on the -export-file FILE option added to kernel-doc in "kernel-doc: add
support for specifying extra files for EXPORT_SYMBOLs", but we extend
that with globbing patterns in the Sphinx extension.
The file patterns are added as options to the :export: and :internal:
arguments of the kernel-doc directive. For example, to extract the
documentation of exported functions from include/net/mac80211.h:
.. kernel-doc:: include/net/mac80211.h
:export: net/mac80211/*.c
Without the file pattern, no exported functions would be found, as the
EXPORT_SYMBOLs are placed in the various source files under
net/mac80211.
The matched files are also added as dependencies on the document in
Sphinx, as they may affect the output. This is one of the reasons to do
the globbing in the Sphinx extension instead of in scripts/kernel-doc.
The file pattern remains optional, and is not needed if the kernel-doc
comments and EXPORT_SYMBOLs are placed in the source file passed in as
the main argument to the kernel-doc directive. This is the most common
case across the kernel source tree.

Scan all input files for EXPORT_SYMBOLs along with the explicitly

If the kernel-doc comments for functions are not in the same file as the
EXPORT_SYMBOL statements, the -export and -internal output selections do
not work as expected. This is typically the case when the kernel-doc
comments are in header files next to the function declarations and the
EXPORT_SYMBOL statements are next to the function definitions in the
source files.
Let the user specify additional source files in which to look for the
EXPORT_SYMBOLs using the new -export-file FILE option, which may be
given multiple times.
The pathological example for this is include/net/mac80211.h, which has
all the kernel-doc documentation for the exported functions defined in a
plethora of source files net/mac80211/*.c.

commit 32217761ee9db0215350dfe1ca4e66f312fb8c54
Author: Jani Nikula <jani.nikula@intel.com>
Date: Sun May 29 09:40:44 2016 +0300
kernel-doc: concatenate contents of colliding sections
we started getting (more) errors on duplicate section names, especially
on the default section name "Description":
include/net/mac80211.h:3174: warning: duplicate section name 'Description'
This is usually caused by a slightly unorthodox placement of parameter
descriptions, like in the above case, and kernel-doc resetting back to
the default section more than once within a kernel-doc comment.
Ignore warnings on the duplicate section name automatically assigned by
kernel-doc, and only consider explicitly user assigned duplicate section
names an issue.

The meaning of "leak" can be both "untracked resource allocation" and
"memory content disclosure". This document's use was entirely of the
latter meaning, so avoid the confusion by using the Common Weakness
Enumeration name for this: Information Exposure (CWE-200). Additionally
adds a section on structure randomization.

Design is pretty simple: kernel-doc inserts breadcrumbs with line
numbers, and sphinx picks them up. At first I went with a sphinx
comment, but inserting those at random places seriously upsets the
parser, and must be filtered. Hence why this version now uses "#define
LINEO " since one of these ever escape into output it's pretty clear
there is a bug.
It seems to work well, and at least the 2-3 errors where sphinx
complained about something that was not correct in kernel-doc text the
line numbers matched up perfectly.
v2: Instead of noodling around in the parser state machine, create
a ViewList and parse it ourselves. This seems to be the recommended
way, per Jani's suggestion.
v3:
- Split out ViewList pach. Splitting the kernel-doc changes from the
sphinx ones isn't possible, since emitting the LINENO lines wreaks
havoc with the rst formatting. We must filter them.
- Improve the regex per Jani's suggestions, and compile it just once
for speed.
- Now that LINENO lines are eaten, also add them to function parameter
descriptions. Much less content and offset than for in-line struct
member descriptions, but still nice to know which exact continuation
line upsets sphinx.
- Simplify/clarify the line +/-1 business a bit.
v4: Split out the scripts/kernel-doc changes and make line-numbers
opt-in, as suggested by Jani.

Opt-in since this wreaks the rst output and must be removed
by consumers again. This is useful to adjust the linenumbers
for included kernel-doc snippets in shinx. With that sphinx
error message will be accurate when there's issues with the
rst-ness of the kernel-doc comments.
Especially when transitioning a new docbook .tmpl to .rst this
is extremely useful, since you can just use your editors compilation
quickfix list to accurately jump from error to error.
v2:
- Also make sure that we filter the LINENO for purpose/at declaration
start so it only shows for selected blocks, not all of them (Jani).
While at it make it a notch more accurate.
- Avoid undefined $lineno issues. I tried filtering these out at the
callsite, but Jani spotted more when linting the entire kernel.
Unamed unions and similar things aren't stored consistently and end
up with an undefined line number (but also no kernel-doc text, just
the parameter type). Simplify things and filter undefined line
numbers in print_lineno() to catch them all.
v3: Fix LINENO 0 issue for kernel-doc comments without @param: lines
or any other special sections that directly jump to the description
after the "name - purpose" line. Only really possible for functions
without parameters. Noticed by Jani.

Further up in the state machinery we switch from STATE_NAME to
STATE_DOCBLOCK when we match /$doc_block/. Which means this block of
code here is entirely unreachable, unless there are multiple DOC:
sections within a single kernel-doc comment.
Getting a list of all the files with more than one DOC: section using
$ git grep -c " * DOC:" | grep -v ":1$"
and then doing a full audit of them reveals there are no such comment
blocks in the kernel.
Supporting multiple DOC: sections in a single kernel-doc comment does
not seem like a recommended way of doing things anyway, so nuke the code
for simplicity.

With this error output becomes almost readable. The line numbers are
still totally bonghits, but that's a lot harder to pull out of
kerneldoc. We'd essentially have to insert some special markers in the
kernel-doc output, split the output along these markers and then
insert each block separately using
state_machine.insert_input(block, source, first_line)

If there are multiple sections with the same section name, the current
implementation results in several sections by the same heading, with the
content duplicated from the last section to all. Even if there's the
error message, a more graceful approach is to combine all the
identically named sections into one, with concatenated contents.
With the supported sections already limited to select few, there are
massively fewer collisions than there used to be, but this is still
useful for e.g. when function parameters are documented in the middle of
a documentation comment, with description spread out above and
below. (This is not a recommended documentation style, but used in the
kernel nonetheless.)
We can now also demote the error to a warning.

kernel-doc currently identifies anything matching "section header:"
(specifically a string of word characters and spaces followed by a
colon) as a new section in the documentation comment, and renders the
section header accordingly.
Unfortunately, this turns all uses of colon into sections, mostly
unintentionally. Considering the output, erroneously creating sections
when not intended is always worse than erroneously not creating sections
when intended. For example, a line with "http://example.com" turns into
a "http" heading followed by "//example.com" in normal text style, which
is quite ugly. OTOH, "WARNING: Beware of the Leopard" is just fine even
if "WARNING" does not turn into a heading.
It is virtually impossible to change all the kernel-doc comments, either
way. The compromise is to pick the most commonly used and depended on
section headers (with variants) and accept them as section headers.
The accepted section headers are, case insensitive:
* description:
* context:
* return:
* returns:
Additionally, case sensitive:
* @return:
All of the above are commonly used in the kernel-doc comments, and will
result in worse output if not identified as section headers. Also,
kernel-doc already has some special handling for all of them, so there's
nothing particularly controversial in adding more special treatment for
them.
While at it, improve the whitespace handling surrounding section
names. Do not consider the whitespace as part of the name.

If a param description spans multiple lines, check any leading
whitespace in the first continuation line, and remove same amount of

Move away from field lists, and simply use **strong emphasis** for
section headings on lines of their own. Do not use rst section headings,
because their nesting depth depends on the surrounding context, which
kernel-doc has no knowledge of. Also, they do not need to end up in any
table of contexts or indexes.
There are two related immediate benefits. Field lists are typically
rendered in two columns, while the new style uses the horizontal width
better. With no extra indent on the left, there's no need to be as fussy
about it. Field lists are more susceptible to indentation problems than
the new style.
