[PATCH 00/30] docs: fix documentation build parsing errors

[Mauro Carvalho Chehab]

Currently, there are several warnings/errors produced when building
the documentation with "make htmldocs".

This series fixes almost all such errors. It is produced against
linux-next, branch next-20200909.

Some of the patches here were already sent individually, but nobody
picked them. So, I'm re-sending the full series.

After this series,  there will be just two parse warnings due to 
Documentation/bpf/ringbuf.rst, which seems to have been
included at linux-next before the actual feature. I already wrote
an e-mail to the author asking for a fix.

There are still plenty warnings produced by kernel-doc, but those
are due to missing files and/or parameters, like:

./include/linux/blk-mq.h:267: warning: Function parameter or member 'active_queues_shared_sbitmap' not described in 'blk_mq_tag_set'
./drivers/gpu/drm/amd/amdgpu/amdgpu_xgmi.c:1: warning: no structured comments found
./drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:675: warning: Excess function parameter 'dev' description in 'amdgpu_device_asic_init'
./drivers/usb/typec/bus.c:1: warning: 'typec_altmode_unregister_driver' not found

As time allows, I will try to cleanup most of those too, although
some may require a deeper knowledge of the affected subsystems.

Jon,

I know that you don't like very much patches against linux-next,
but that seems to be the only way to address issues when building
the docs, as warnings can come from random trees.

My suggestion would be for you to pick at least the ones that apply
cleanly on your tree.  I can rebase the ones later for them to be
applied along the merge window.

I'm aiming here to have Kernel 5.10 free of documentation
warnings. Hopefully, people will take more care to avoid
introducing new warnings once we get rid of all of them.

[PATCH 01/30] .gitignore: docs: ignore sphinx_*/ directories

[Mauro Carvalho Chehab]

The default way of building documentation is to use
Sphinx toolchain installed via pip, inside the
Kernel tree main directory. That's what's recommended by:

	scripts/sphinx-pre-install

As it usually provides a better version of this package
than the one installed, specially on LTS distros.

So, add the directories created by running the commands
suggested by the script.

[PATCH 03/30] dt-bindings: fix references to files converted to yaml

[Mauro Carvalho Chehab]

There were several files converted to yaml, but the .txt file
is still referenced somewhere else.

Update the references for them to point to the right file.

Using "@bio's parent" causes the following waring:

The main problem here is that this would be converted into:

	**bio**'s parent

By kernel-doc, which is not a valid notation. It would be
possible to use, instead, this kernel-doc markup:

	``bio's`` parent

Yet, here, is probably simpler to just use an altenative language:

Currently, sphinx emits one warning on this file:

That's due to some extra spaces before the title of a chapter.

[PATCH 21/30] iio: industrialio-core.c: solve a kernel-doc warning

[Mauro Carvalho Chehab]

kernel-doc currently compains with:
	./drivers/iio/industrialio-core.c:177: warning: Function parameter or member 'indio_dev' not described in 'iio_get_debugfs_dentry'
	./drivers/iio/industrialio-core.c:1530: warning: Function parameter or member 'parent' not described in 'iio_device_alloc'

The problem is that the comment just before iio_get_debugfs_dentry()
is just a comment, and not really a kernel-doc markup.

[PATCH 22/30] kunit: test.h: solve kernel-doc warnings

[Mauro Carvalho Chehab]

There are some warnings there:

	./include/kunit/test.h:353: warning: Function parameter or member 'res' not described in 'kunit_add_resource'

	./include/kunit/test.h:367: warning: Excess function parameter 'name_data' description in 'kunit_add_named_resource'

Address them, ensuring that all non-private arguments will
be properly described. With that regards, at struct kunit_resource,
the free argument is described as user-provided. So, this
doesn't seem to belong to the "private" part of the struct.

[PATCH 23/30] docs: submitting-patches: use :doc: for references

[Mauro Carvalho Chehab]

There are two broken references at submitting-patches.rst:

	Documentation/process/submitting-patches.rst:240: WARNING: undefined label: security-bugs (if the link has no caption the label must precede a section header)
	Documentation/process/submitting-patches.rst:336: WARNING: undefined label: documentation/process/email-clients.rst (if the link has no caption the label must precede a section header)

Those are due to some recent renames and file moves.

It turns that maintaining :ref: is currently harder than using
:doc:, as we now have a script to help checking such references.

So, replace :ref: to :doc: there, making them to point to the
current file name.

[PATCH 24/30] docs: lockdep-design: fix some warning issues

[Mauro Carvalho Chehab]

There are several warnings caused by a recent change
224ec489d3cd ("lockdep/Documention: Recursive read lock detection reasoning")

Those are reported by htmldocs build:

    Documentation/locking/lockdep-design.rst:457: WARNING: Unexpected indentation.
    Documentation/locking/lockdep-design.rst:457: WARNING: Blank line required after table.

Besides the reported issues, there are some missing blank
lines that ended producing wrong html output, and some
literals are not properly identified.

Also, the symbols used at the irq enabled/disable table
are not displayed as expected, as they're not literals.
Also, on another table they're using a different notation.

[Mauro Carvalho Chehab]

There's a warning at iio.h kernel-doc markup:

Because it is using {devm_}foo notation. Well, this is not
a valid kernel-doc notation. Also, it prevents creating hyperlinks
to other documentation functions.

So, replace it to a better notation.

This still stands from last posting:

Reviewed-by: Valentin Schneider <valentin.schneider@arm.com>

In the cover letter you mention resending a bunch of these (including this
one) as they weren't picked up. Ingo / Peter, would you guys mind picking
this one up in tip? AFAICT it's the only scheduler-related patch of the
series.

I'd sure love to just apply the whole series and clean up a lot of this
stuff, but (1) I'm not entirely comfortable taking a few through
docs-next, and (2) some of them don't apply even if I catch up to -rc4.
So I'm going to pass through them individually and snag as many as I can...

Thanks,

jon

Applied, thanks.

Also applied parts 2, 5, 6, 7, 12, 14, 16, 17, 19, 20, and 23.  Many of
the others don't apply at all; they're going to need to go to the relevant
maintainers.

Thanks,

Yeah. As I commented on the other series, as warnings reach upstream
from different trees, the only sane way to fix them is by using linux-next.

I'll keep rebase those. This way, if something ends being lost, we could
submit upstream by the end of the merge window.

Btw, as Andrii gently submitted a fix for the two remaining litmus doc
warnings, once everything gets merged, htmldocs should now produce
zero doc warnings.

I'll keep track on this. Hopefully, we can make 5.10 free of doc warnings,
and build robots can start warning about newly introduced ones.

Thanks,
Mauro

Not much going on in that file at the moment, so fine if Jon picks this
up directly.
