The patch is OK, but its subject is wrong.

The patch above isn't fixing any syntax errors, but rather minor cleanup.
The subject should have been "Remove duplicate 'to' in the
flush_dcache_page() comment".

I think that this kind of cleanup patches (typofixes) are best done
as part of **actual** work on the code in question (for example
refactoring or fixing build errors).

Thanks.

So code that is fine will have typos forever?  Fixing typos in comments
doesn't break git blame for the following code.  And typos in comments
give a bad impression about the state of the code in general.

But that is a general statement.  Perhaps this code does particularly need
work.

Of course not! Documentation is as important as the code, if not even more.
However, fixing typos to increase your commit counts to a reputable project
is not fine either. For instance, many of these proposed fixes are targeting
one single typo at a time. Couldn't they just be sent altogether!?!

I have the impression that the person is just trying to figure out the
patch submission process.  For example, the subject lines are not
formatter in the standard way (I sent the person a private email about
that).  Perhaps just let him know about how you would rather have received
the patches.

In recent times I had seen many typofix patches sent to LKML. You can see most
of them by querying `s:"fix typo"` on lore.kernel.org. Some of these patches
have been merged, though.

What I say as starter thread is "ideal" scenario as described in
Documentation/process/2.Process.rst; that is we prefer to see these minor
fixes as part of real patches work (say refactoring), rather than just being
trivial patches.

But what most reviewers here missed is how these typos are found? I guess
these can be from codespell or some other tools, or even manual review,
then send the fixes en mass.

Take a look at "fix typo in a comment" aka "delete redundant word" patches
at [1], [2], [3]. and [4].

[1]: https://lore.kernel.org/lkml/20220618132659.17100-1-wangxiang@cdjrlc.com/
[2]: https://lore.kernel.org/lkml/20220618130349.11507-1-wangxiang@cdjrlc.com/
[3]: https://lore.kernel.org/lkml/20220616163830.11366-1-wangxiang@cdjrlc.com/
[4]: https://lore.kernel.org/lkml/20220606123419.29109-1-wangxiang@cdjrlc.com/

IMHO, these patches should have been in a single, consolidated patch, since
these strip duplicate (hence redundant) word (single logical change).

Thanks.

They go to different maintainers, so perhaps each one would prefer to get
their own patches?  There was a trivial tree, but it is apparently not
very active.

It would indeed be good to indicate how the problems were found.  That
could suggest whether the problem has been addressed comprehensively, or
whether just some random issues have been detected.

It would be interesting to see what tool it is, because there appear to be
a bunch of false positives (although maybe that is on the user to read and
understand the tool's output)

I'd just say "ARC: mm: fix typos"

In an ideal world yes. But sometimes maintainer complain to break 
whitespacxe fixes and such into independent fix. Also as someone said 
later in the thread, for somebody just getting into kernel and figuring 
out patch submission etc this could be a perfect dry run and helps 
improve the code anyways.

Seems like you missed the point that it's OK to have typofixes while
doing other real changes (like refactoring) in the same patch.

I tend to agree with the last sentence of above quote. Let's pretend that
I'm the tree maintainer. Besides reviewing real change patches, I get
flooded by these similar minor cleanup patches that I need to review.
Some (but not all) these patches have issues (say subject or description
error) that are repeated. Lazily speaking, I'd like to privately notice the
submitter about the situation, and I withhold these for now.

Thanks.

No I did not.

"Repeated" is the key - First time I'd politely tell them to DTRT but 
will just ignore if things continue.

Funny that you say this: ever since this got posted I now see 3 patches 
for typo fixes :-)
But it is something in maintainers purview and for now i'm ok.
