My bisect scripts starting running into build failures when trying to
compile 4.15-rc1 with the builds failing with things like:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c:2078: error: Cannot parse struct or union!
The line in question is actually just a #define, but after some digging
it turns out that my scripts pass W=1 and since commit 3a025e1d1c
("Add optional check for bad kernel-doc comments") that results in
kernel-doc running on each source file. The file in question has a
badly formatted comment immediately before the #define:
/**
* struct brcmf_skbuff_cb reserves first two bytes in sk_buff::cb for
* bus layer usage.
*/
which causes the regex in dump_struct to fail (lack of braces following
struct declaration) and kernel-doc returns 1, which causes the build
to fail.
Fix the issue by always returning 0 from kernel-doc when invoked with
-none. It successfully generates no documentation, and prints out any
issues.

18/01/2001 - Cleanups
Functions prototyped as foo(void) same as foo()
Stop eval'ing where we don't need to.
-- huggie@earth.li
27/06/2001 - Allowed whitespace after initial "/**" and
allowed comments before function declarations.
-- Christian Kreibich ck@whoop.org
Still to do:
- add perldoc documentation
- Look more closely at some of the scarier bits :)
26/05/2001 - Support for separate source and object trees.
Return error code.
Keith Owens kaos@ocs.com.au
23/09/2001 - Added support for typedefs, structs, enums and unions
Support for Context section; can be terminated using empty line
Small fixes (like spaces vs. \s in regex)
-- Tim Jansen tim@tjansen.de
25/07/2012 - Added support for HTML5
-- Dan Luedtke mail@danrl.de

Read C language source or header FILEs, extract embedded documentation comments, and print formatted documentation to standard output.
The documentation comments are identified by "/**" opening comment mark. See Documentation/kernel-doc-nano-HOWTO.txt for the documentation comment syntax.
Output format selection (mutually exclusive): -docbook Output DocBook format. -html Output HTML format. -html5 Output HTML5 format. -list Output symbol list format. This is for use by docproc. -man Output troff manual page format. This is the default. -rst Output reStructuredText format. -text Output plain text format. -none Do not output documentation, only warnings.
Output selection (mutually exclusive): -export Only output documentation for symbols that have been exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() in any input FILE or -export-file FILE. -internal Only output documentation for symbols that have NOT been exported using EXPORT_SYMBOL() or EXPORT_SYMBOL_GPL() in any input FILE or -export-file FILE. -function NAME Only output documentation for the given function(s) or DOC: section title(s). All other functions and DOC: sections are ignored. May be specified multiple times. -nofunction NAME Do NOT output documentation for the given function(s); only output documentation for the other functions and DOC: sections. May be specified multiple times.
Output selection modifiers: -no-doc-sections Do not output DOC: sections. -enable-lineno Enable output of #define LINENO lines. Only works with reStructuredText format. -export-file FILE Specify an additional FILE in which to look for EXPORT_SYMBOL() and EXPORT_SYMBOL_GPL(). To be used with -export or -internal. May be specified multiple times.
Other parameters: -v Verbose output, more warnings and other information. -h Print this help.

format of comments.
In the following table, (...)? signifies optional structure.
(...)* signifies 0 or more structure elements
/**
* function_name(:)? (- short description)?
(* @parameterx: (description of parameter x)?)*
(* a blank line)?
* (Description:)? (Description of function)?
* (section header: (section description)? )*
()?/
So .. the trivial example would be:
/**
* my_function
*/
If the Description: header tag is omitted, then there must be a blank line
after the last parameter specification.
e.g.
/**
* my_function - does my stuff
* @my_arg: its mine damnit
*
* Does my stuff explained.
*/
or, could also use:
/**
* my_function - does my stuff
* @my_arg: its mine damnit
* Description: Does my stuff explained.
*/
etc.
Besides functions you can also write documentation for structs, unions,
enums and typedefs. Instead of the function name you must write the name
of the declaration; the struct/union/enum/typedef must always precede
the name. Nesting of declarations is not supported.
Use the argument mechanism to document members or constants.
e.g.
/**
* struct my_struct - short description
* @a: first member
* @b: second member
*
* Longer description
*/
struct my_struct {
int a;
int b;
/* private: */
int c;
};
All descriptions can be multiline, except the short function description.
For really longs structs, you can also describe arguments inside the
body of the struct.
eg.
/**
* struct my_struct - short description
* @a: first member
* @b: second member
*
* Longer description
*/
struct my_struct {
int a;
int b;
/**
* @c: This is longer description of C
*
* You can use paragraphs to describe arguments
* using this method.
*/
int c;
};
This should be use only for struct/enum members.
You can also add additional sections. When documenting kernel functions you
should document the "Context:" of the function, e.g. whether the functions
can be called form interrupts. Unlike other sections you can end it with an
empty line.
A non-void function should have a "Return:" section describing the return
value(s).
Example-sections should contain the string EXAMPLE so that they are marked
appropriately in DocBook.
Example:
/**
* user_function - function that can only be called in user context
* @a: some argument
* Context: !in_interrupt()
*
* Some description
* Example:
* user_function(22);
*/
...
All descriptive text is further processed, scanning for the following special
patterns, which are highlighted appropriately.
'funcname()' - function
'$ENVVAR' - environmental variable
'&struct_name' - name of a structure (up to two words including 'struct')
'&struct_name.member' - name of a structure member
'@parameter' - name of a parameter
'%CONST' - name of a constant.
'LITERAL
' - literal string without any spaces on it.

Essentially these are globals.
They probably want to be tidied up, made more localised or something.
CAVEAT EMPTOR! Some of the others I localised may not want to be, which
could cause "use of undefined value" or other bugs.
