The change from \d+ to .+ inside __aligned() means that the following
structure:
struct test {
u8 a __aligned(2);
u8 b __aligned(2);
};
essentially gets modified to
struct test {
u8 a;
};
for purposes of kernel-doc, thus dropping a struct member, which in
turns causes warnings and invalid kernel-doc generation.
Fix this by replacing the catch-all (".") with anything that's not a
semicolon ("[^;]").
Fixes: 9dc30918b2 ("scripts/kernel-doc: handle struct member __aligned without numbers")

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
This will read a 'c' file and scan for embedded comments in the
style of gnome comments (+minor extensions - see below).
Note: This only supports 'c'.
usage:
kernel-doc [ -docbook | -html | -html5 | -text | -man | -list ]
[ -no-doc-sections ]
[ -function funcname [ -function funcname ...] ]
c file(s)s > outputfile
or
[ -nofunction funcname [ -function funcname ...] ]
c file(s)s > outputfile
Set output format using one of -docbook -html -html5 -text or -man.
Default is man.
The -list format is for internal use by docproc.
-no-doc-sections
Do not output DOC: sections
-function funcname
If set, then only generate documentation for the given function(s) or
DOC: section titles. All other functions and DOC: sections are ignored.
-nofunction funcname
If set, then only generate documentation for the other function(s)/DOC:
sections. Cannot be used together with -function (yes, that's a bug --
perl hackers can fix it 8))
c files - list of 'c' files to process
All output goes to stdout, with errors to stderr.
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.
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')
'@parameter' - name of a parameter
'%CONST' - name of a constant.
init lots of data
my $errors = 0; my $warnings = 0; my $anon_struct_union = 0;

Output conversion substitutions.
One for each output format
these work fairly well

my %highlights_html5 = ( $type_constant, "<span class="const">$1", $type_func, "<span class="func">$1", $type_struct_xml, "<span class="struct">$1", $type_env, "<span class="env">$1", $type_param, "<span class="param">$1" ); my $blankline_html5 = $local_lt . "br /" . $local_gt;
XML, docbook format
my %highlights_xml = ( "([^=])\"([^\"<]+)\"", "$1$2", $type_constant, "$1", $type_func, "$1", $type_struct_xml, "$1", $type_env, "$1", $type_param, "$1" ); my $blankline_xml = $local_lt . "/para" . $local_gt . $local_lt . "para" . $local_gt . "\n";
gnome, docbook format
my %highlights_gnome = ( $type_constant, "<replaceable class="option">$1", $type_func, "$1", $type_struct, "$1", $type_env, "$1", $type_param, "$1" ); my $blankline_gnome = "\n";
these are pretty rough
my %highlights_man = ( $type_constant, "$1", $type_func, "\\fB$1\\fP", $type_struct, "\\fI$1\\fP", $type_param, "\\fI$1\\fP" ); my $blankline_man = "";
text-mode
my %highlights_text = ( $type_constant, "$1", $type_func, "$1", $type_struct, "$1", $type_param, "$1" ); my $blankline_text = "";
list mode
my %highlights_list = ( $type_constant, "$1", $type_func, "$1", $type_struct, "$1", $type_param, "$1" ); my $blankline_list = "";
read arguments
if ($#ARGV == -1) { usage(); }
my $kernelversion; my $dohighlight = "";
my $verbose = 0; my $output_mode = "man"; my $output_preformatted = 0; my $no_doc_sections = 0; my %highlights = %highlights_man; my $blankline = $blankline_man; my $modulename = "Kernel API"; my $function_only = 0; my $man_date = ('January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December')[(localtime)[4]] .

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.
