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).

DOC: blocks were not escaped thru xml_escape() like other kernel-doc

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

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.
