Thanks for mentioning.

I too recall that seemingly redundant entries were noticed during
the review and at least back then removing the seemingly redundant
ones caused failures in rewriting.

That is why I am hesitant to touch any patch that says "simplify
cocci rule" making it sound as if simplification is a good thing on
its own.  I have no problem with "we change the rule this way, which
eliminates this false positive / negative, that is demonstrated in
the added tests in t/ directory", though.

Thanks.
