This says _what_ you do.  But we can see that in the patch itself.

You need to say _why_ you are doing this.

There's no need for this change at all.  Again, as I have said before,
we write code for developers to read first, the compiler second.  By
making these types of changes you are making it harder to
read/understand by a developer, and providing absolutely no benifit to
the compiler at all.

So it's actually making the code worse!

not good at all.

Please reconsider this type of change, as I keep asking you to.
