I'm sorry, I wouldn't normally respond to this, but I was put on the Cc
after all so I'll give my feedback.

I think these patches are a waste of time and a resources.

It would be different if your patches fixed actual bugs. This is just
mindless code transformations that MAY in the best case save a few bytes
of code here and there (I don't know; you didn't say).

But the potential gains from these incredibly numerous and tiny patches
that don't fix anything are so small, it's a waste of time, bandwidth,
and mental capacity for you and for everybody involved.

I just searched my inbox for patches from you and you sent literally
_hundreds_ over the past few days, all doing this crazy printf/puts/putc
transformation.

Another bit of searching and I see that I'm not the first one giving you
this response:

https://lkml.org/lkml/2016/10/7/148 - Dan Carpenter

...and I'm sure there are many more.
