[PATCH 1/2] cpumask: Fix kernel-doc formatting errors in cpumask.h

[Viresh Kumar]

This fixes various kernel-doc formatting errors in cpumask.h:

- WARNING: Inline literal start-string without end-string.
- ERROR: Unexpected indentation.
- ERROR: Unknown target name: "gfp".

[PATCH 2/2] docs: core-api: Update kernel-api.rst to include cpumask.h

[Viresh Kumar]

Updated Documentation/core-api/kernel-api.rst to include `cpumask.h`,
providing better reference for CPU mask operations in the kernel API.

kernel-doc (script) can recognize the pattern of %*pb but not %*pb[l].
"%*bp [l]" should work here.
(without quotes and a white space in front of "[").

No need to escape "%".

kernel-doc (script) understands the pattern of *@srcp1.
No need to escape "*".

But it does not (yet) parse the pattern of "*@n+1".  You need to say
"*@n +1", with a space in front of "+1", for the time being.

Do you really want those code-blocks to look fancy?

In kernel-doc comments, I'd normally use plain literal blocks instead.

Something like:

 * This saves a temporary CPU mask in many places.  It is equivalent to::
 *
 *	struct cpumask tmp;
 *	cpumask_and(&tmp, &mask1, &mask2);
 *	for_each_cpu(cpu, &tmp)

should work.  Note the "::" and the empty line below it.

You can say:

instead.

Side note:

I think 1/2 would be better to be CC'ed linux-doc as well.
Please do so in respin.

Yes, please don't do it. The comments first and foremost should be a
human-readable text. If we add C code, it should stay a C code.

I agree. I'm all for covering cpumasks documentation with kernel-doc,
but it should stay readable after that.

That would be great!

At the moment, re-implementation of kernel-doc into python is under way [1].

[1]: https://lore.kernel.org/cover.1740387599.git.mchehab+huawei@kernel.org/

It is a bug compatible porting from perl to python3, but it is likely
to be merged during 6.16 merge window.

I think it would be nicer to do the fix on top of python3 kernel-doc
after that happens.

        Thanks, Akira
