Pardon my ignorance, but this is the first I've seen of kernel-doc warnings.
Is there a flag I can set when I build to get kernel-doc warnings? Is there a tool I can run?
Where is the kernel-doc format documented? I'd like to avoid this in the future.
Here is the 0day bot report:
(not sent to any of your group, sadly).
kernel-doc format is documented in Documentation/doc-guide/kernel-doc.rst.
The 0day bot lists the reproduction steps. It used clang but I used
gcc. Shouldn't matter in this case. The main point from the 0day bot
is that "this is a W=1 build". Using W=1 causes checks for extra
C compiler warnings and also it causes checks for documentation build
In your build environment, using "make W=1 ARCH=s390 allmodconfig all"
will produce lots of output (both compiler and kernel-doc output).
I suppose that is the expected way to do it.
AFAIK there is no support for something like "make W=1 htmldocs"
to just check for kernel-doc errors/warnings in source files, so what
I do when I am targeting only one source file is something like what
is documented in the file referenced above:
"Running the ``kernel-doc`` tool with increased verbosity and without actual
output generation may be used to verify proper formatting of the
documentation comments. For example::
scripts/kernel-doc -v -none drivers/foo/bar.c
and then I script that for ease of use.
Using the latter command reports lots more kernel-doc warnings than
the 0day bot reported, so I fixed all of them that it found.

There are no more kernel-doc errors or warnings reported in this file.
