[PATCH v3 00/23] Fix some issues at documentation

[Mauro Carvalho Chehab]

Hi Jon,

This series is against today's next (next-20211019) and addresses missing
links to Documentation/*.

The best would be to have the patches applied directly to the trees that
contain the patches that moved/renamed files, and then apply the
remaining ones either later during the merge window or just afterwards,
whatever works best for you.

Regards,
Mauro

[PATCH v3 01/23] visorbus: fix a copyright symbol that was bad encoded

[Mauro Carvalho Chehab]

The copyright symbol was badly encoded using the
REPLACEMENT CHARACTER U+fffd ('�'), probably due to some
bad charset conversion.

Fix it.

[PATCH v3 03/23] docs: accounting: update delay-accounting.rst reference

[Mauro Carvalho Chehab]

The file name: accounting/delay-accounting.rst
should be, instead: Documentation/accounting/delay-accounting.rst.

Also, there's no need to use doc:`foo`, as automarkup.py will
automatically handle plain text mentions to Documentation/
files.

So, update its cross-reference accordingly.

[PATCH v3 19/23] Documentation/process: fix a cross reference

[Mauro Carvalho Chehab]

The cross-reference for the handbooks section works. However, it is
meant to describe the path inside the Kernel's doc where the section
is, but there's an space instead of a dash, plus it lacks the .rst at
the end, which makes:

	./scripts/documentation-file-ref-check

to complain.

No, this change is incorrect. We have discussed it several times before

It'd be a bit easier to put a note in here about what the dependencies
are rather than forcing people to go out to a link to figure out what's
going on unless it's complicated.  For a case like this where there's no
dependencies or real relationship between the patches it's probably
better to just not thread everything and send the patches separately to
everyone, the threading is just adding noise and confusion.

Could we delete the rest too?

We don't do those changelog-style comments any more; they're in the git
history if you need them.  I can sort of get leaving some in out of
respect or if they've still provide some useful information.  But
keeping comments referring to code that doesn't even exist any more just
seems confusing.

IDK...Do we want to "erase history" selectively like that?

Maybe we should just get rid of the whole pile of "changelog" comments
in fs/locks.c? They aren't terribly useful these days anyhow.

...  that'd be fine with me.

I didn't mainly because I thought it'd be good to read through it and
see if there's anything that should be salvaged.

Reading through it now:

The last few paragraphs (under "Locking conflicts and dependencies" were
added more recently by Neil and are still useful.

I'd be OK losing the rest.

It might still be good to have some basic introduction; maybe something
like this?:

Yeah, I think that looks great. Send it with a changelog and I'll pull
it into the branch I have feeding into -next.

[PATCH] locks: remove changelog comments

[J. Bruce Fields]

From: "J. Bruce Fields" <bfields@redhat.com>

This is only of historical interest, and anyone interested in the
history can dig out an old version of locks.c from from git.

Triggered by the observation that it references the now-removed
Documentation/filesystems/mandatory-locking.rst.

Reported-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

Thanks, Bruce (and Mauro). Applied to the locks-next branch (and I
dropped Mauro's patch that touched the same area). It should make v5.16.

It is not that easy, unfortunately. On some cases (specially due to
DT binding renames) some patches change the context of a hunk, affecting
a subsequent patch.

I tried a couple of times in the past to send the patches individually,
but that was messier, as there was harder for people to apply them,
as, instead of running b4 just once to get everything, maintainers
would need to apply each patch individually. Also, there were cases
where the patch order would be relevant, due to context changes.

-

Btw, talking about what it would be easier, the best procedure to
adopt is to run:

	./scripts/documentation-file-ref-check 

Before sending/applying patches touching documents.

That would avoid the need of such fixup patches ;-)

Unfortunately, in the specific case of dt-bindings, things are not
that easy, as doc changes usually go via one tree, while references 
to them come from other places.

Mauro

If that's the case then the cover letter really needs work to make this
clear, I couldn't tell that there was any risk of dependencies nor would
I expect any for such trivial changes.

You could also send a per subsystem series if there's a concern about it
being hard to pick up individual patches.

It'd be great if Rob or you can apply this patch, I have sent my Gemini

Those should be reduced now. I've been checking the renames since early 
August. July really, but MAINTAINERS was not getting checked initially.

Just spliting between in Linus' tree and only in next would help me. The 
former I know I can just apply.

cc to the translation maintainers and translator would be helpful?

Uh, I don't know other languages, but in Chinese, 15 years before
translated books are still selling well in China. :)

Dear David

Thank you very much for your contribution, in fact, we are always updating the
translations and improving the speed of the sync, so If you are not
good at Chinese
and want to get the sync faster, please CC us when you send the patch.

Alex,Maybe we should provide a translation guide in English, e.g::

  Dear developers, if you have trouble updating the Chinese documentation after
  updating the original documentation, please CC the translator of
that documentation
  and the maintainer of the Chinese documentation, and the relevant
documentation
  will be updated soon.

It would be great if we would get this suggestion automatically, e.g.,
via get_maintainers.pl --- maybe that's already done, I didn't check.

Personally, I don't speak/read any Chinese, so I'm mostly lost staring
at the Chinese translation. :)

Yes, these books in particular are still of a lot of value, although
outdated. :)

The difference is that when you translate a book, there is a
date/version attached, meaning, the original book was for example based
on kernel v2.XXX. Once you translate the book, it's simply based on the
same kernel version.

The in-tree doc is similar. You can access the v5.14 doc for example
easily via https://www.kernel.org/doc/html/v5.14/. And the Chinese
version via https://www.kernel.org/doc/html/v5.14/translations/zh_CN/.

If I as a developer perform a doc update in v5.14, and the translation
isn't updated until the end of the same release, the versioned
documentation will be out of sync. And that happens automatically with a
new release.

With an out-of-tree translation, there wouldn't really be an issue. Once
everything was translated (brought up-to-date), you would mark it has
"fully translated doc of v5.15" manually and release it.

But maybe the translation maintainers already take proper care of
updating any translation just before the new kernel is released.

So just my comment after stumbling over in-tree doc translations.
