Yes, it's a script that finds lots of false positives, so I have to check
each and every one of them for validity.

Thanks for noticing that.

I checked all of my emails for this patch series and they say that Mike was Cc:ed
on all of them.

I am adding his email address back to this one.
Mike, did you receive this patch series?

And it's a lot of work too. (thanks Randy)

It could be something like:

$ grep-2.5.4 -nrP --include=*.[ch] '\b([A-Z]?[a-z]{2,}\b)[ \t]*(?:\n[ \t]*\*[ \t]*|)\1\b' * | \

Hi Joe,

(what is grep-2.5.4 ?)

It looks like you tried a few iterations of this -- since it drops things
like "long long".  There are lots of data types that are repeated & valid.
And many struct names, like "struct kref kref", "struct completion completion",
and "struct mutex mutex".  I handle (ignore) those manually, although that
could be added to the Perl script.

v0.1 of this script also found lots of repeated numbers and strings of
special characters (ASCII art etc.), so now it ignores duplicated numbers
or special characters -- since it is really looking for duplicate words.

Anyway, I might as well attach it. It's no big deal.
And if someone else wants to tackle using it, go for it.

It's the last version of grep that allowed spanning multiple lines.

That's to find the comment second lines that start with *

Yes.

There's a mailman option which drops me from being explicity on Cc,
because I'm subscribed to the list. Otherwise I get two copies of
everything.

So as long as it goes to linuxppc-dev I should see it, regardless of
whether I'm explicitly listed in Cc.

This might be a reasonable thing to add to checkpatch.

And here's another possible similar perl word deduplicator attached:

Assuming you have git, this could be used like:

$ git ls-files -- <dir> | xargs perl deduplicate_words.pl

And it would overwrite all files with duplicated words.

No guarantees any changes it makes are right of course.
It still needs a human to verify any change.

[PATCH] checkpatch: Add test for repeated words

[Joe Perches]

Try to avoid adding repeated words either on the
same line or consecutive comment lines in a block

e.g.:

duplicated word in comment block

	/*
	 * this is a comment block where the last word of the previous
	 * previous line is also the first word of the next line
	 */

and simple duplication

	/* test this this again */

No charge.

It seemed simple enough and you are/were doing
an awful lot of work to fix these.

Thanks for that too.
