Having some extra warnings were already expected ;-)
The problem is that a kernel-doc markup like:
/**
* foo() - some desciption
*/
void bar(void) {}
Produces:
.. c:function:: void bar (void)
some desciption
**Parameters**
``void``
no argument
In other words, kernel-doc documents function "bar()", using the text
from the function "foo()" markup.
While, on several cases, this is what it was expected, we've got several
problems already, where some other function was added between
the kernel-doc markup and the function it documents, causing
troubles on its documentation.
So, we added a kernel-doc warning to let the developers to know
that the function documented has a different name on its kernel-doc
markup.
Thanks,
Mauro
