If a function has a return value, but its kernel-doc comment doesn't contain a
"Return" section, then emit the following warning:
Warning(file.h:129): No description found for return value of 'fct'
Note: This check emits a lot of warnings at the moment, because many functions
don't have a 'Return' doc section. So until the number of warnings goes
sufficiently down, the check is only performed in verbose mode.

- Support for a cleaner html output in scripts/kernel-doc, named
html5 (no, it does not play videos, yet)
BTW, Randy wants to route further kernel-doc patches through the

* 'misc' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
Update SmPL/Coccinelle section of MAINTAINERS
coccicheck: Add the rep+ctxt mode
scripts/coccinelle/tests/odd_ptr_err.cocci: semantic patch for IS_ERR/PTR_ERR inconsistency
scripts/tags.sh: Add magic for pci access functions
scripts/coccinelle: ptr_ret: Add ternary operator version
scripts/kernel-doc: drop maintainer
scripts/kernel-doc: added support for html5
A section with the name "Example" (case-insensitive) has a special meaning
to kernel-doc. These sections are output using mono-type fonts. However,
leading whitespace is stripped, thus robbing a lot of meaning from this,
as indented code examples will be mangled.
This patch preserves the leading whitespace for "Example" sections. More
accurately, it preserves it for all sections, but removes it later if the
section isn't an "Example" section.

Move 'main' code vs. subroutines around so that they are not so
intermixed, for better readability/understanding (relative to Perl).
It was messy to follow the primary flow of code execution with the
code being mixed. Now the code begins with data initialization,
followed by all subroutines, then ends with the main code execution.
This is almost totally source code movement, with a few changes as
needed for forward declarations.

scripts/kernel-doc mishandles a function that has a multi-line function
short description and no function parameters. The observed problem was
from drivers/scsi/scsi_netlink.c:
/**
* scsi_netlink_init - Called by SCSI subsystem to intialize
* the SCSI transport netlink interface
*
**/
kernel-doc treated the " * " line as a Description: section with only a
newline character in the Description contents. This caused
output_highlight() to complain: "output_highlight got called with no

The introduction of the new 'DECLARE_EVENT_CLASS()' obviates the
need for the 'TRACE_EVENT()' macro in some cases. Thus, docbook
style comments that used to live with 'TRACE_EVENT()' are now
moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook
system understand the new 'DEFINE_EVENT()' macro. In addition
I've tried to futureproof the patch, by also adding support for
'DEFINE_SINGLE_EVENT()', since there has been discussion about
renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT().
Without this patch the tracepoint docbook fails to build.
I've verified that this patch correctly builds the tracepoint
docbook which currently covers signals, and irqs.

I saw this problem recently. With this kernel-doc:
* Note: some important info
*
* Note: other important info
kernel-doc uses the "section name" (preceding the ':', like "Note") as a hash
key for storing the descriptive text ("blah important info"). It is (was)
possible to have duplicate (colliding) section names, without any kind of
warning or error.
kernel-doc happily used the latter descriptive text for all instances of
printing the <section-name> descriptive text and the former important info
was lost.
One way to "fix" this is to modify the kernel-doc comments, e.g.:
* Note1: foo bar
*
* Note.2: blah zay
For now, kernel-doc will signal an error when it sees colliding section names
like this.

When running "make htmldocs" I'm seeing some non-fatal perl errors caused
by trying to parse the callback function definitions in blk-core.c.
The errors are "Use of uninitialized value in concatenation (.)..."
in combination with:
Warning(linux-2.6.25-rc2/block/blk-core.c:1877): No description found for parameter ''
The function pointers are defined without a * i.e.
int (drv_callback)(struct request *)
The compiler is happy with them, but kernel-doc isn't.
This patch teaches create_parameterlist in kernel-doc to parse this type of
function pointer definition, but is it the right way to fix the problem ?
The problem only seems to occur in blk-core.c.
However with the patch applied, kernel-doc finds the correct parameter
description for the callback in blk_end_request_callback, which is doesn't
normally.
I thought it would be a bit odd to change to code to use the more normal
form of function pointers just to get the documentation to work, so I fixed
kernel-doc instead - even though this is teaching it to understand code
that might go away (The comment for blk_end_request_callback says that it
should not be used and will removed at some point).

Johannes Berg reports (Thanks!) that &struct names are not highlighted in
html output format when they are inside a DOC: block.
DOC: blocks were not escaped thru xml_escape() like other kernel-doc
comments were. Fixed that.
However, that left a problem with <p> ($blankline_html) being processed
thru xml_escape(), converting it to <p>, which isn't good for the
generated html output (the <p> should remain unchanged), so this patch also
introduces the notion of "local" kernel-doc meta-characters
('\\\\mnemonic:'), which are converted to html just before writing the
stream to its output file.
Please report any problems that you (anyone) see in "highlighting" in any
output mode (text, man, html, xml).
Also update copyright to include me.

In a different approach here's a patch that handles the special case of
composite arithmetic expressions in array size initializers. With it,
prior to pushing the split strings on the @first_arg array, I split the
keywords before the array name as before and then keep the array name along
with the subscript expression as a single whole element which gets pushed
last. In this manner, kernel-doc produces correct output without removing
whitespaces which makes the array subscripts unreadable in the docs.

When the verbose (-v) option is used with scripts/kernel-doc, this option
reports when the kernel-doc format is malformed and apparently contains
function description lines before function parameters. In these cases, the

I have fixed the problems in mm/filemap.c and added lots of kernel-doc to

"Section" data (contents) are split from the section header
(e.g., Note: below is a section header:

Currently the data/contents begins with a space and is left that way, which
causes it to look bad when printed (in text mode; see example below), so
just remove the leading space.

I have recompiled Linux kernel 2.6.11.5 documentation for me and our
university students again. The documentation could be extended for more
sources which are equipped by structured comments for recent 2.6 kernels. I
have tried to proceed with that task. I have done that more times from 2.6.0
time and it gets boring to do same changes again and again. Linux kernel
compiles after changes for i386 and ARM targets. I have added references to
some more files into kernel-api book, I have added some section names as well.
So please, check that changes do not break something and that categories are
not too much skewed.
I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
by kernel convention. Most of the other changes are modifications in the
comments to make kernel-doc happy, accept some parameters description and do
not bail out on errors. Changed <pid> to @pid in the description, moved some
#ifdef before comments to correct function to comments bindings, etc.
You can see result of the modified documentation build at
http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz
Some more sources are ready to be included into kernel-doc generated
documentation. Sources has been added into kernel-api for now. Some more
section names added and probably some more chaos introduced as result of quick
cleanup work.
