Subject: Re: [PATCH] kbuild: Allow to combine multiple W= levels

I'm really getting tired of this!

No, because we need to get a feeling of what makes sense for all these
options first. I'd rather do the learning-by-doing thing here and
implement what makes sense than braindead frameworks.

WTF? http://marc.info/?l=linux-kbuild&m=130346037604547&w=2

No one else did check those and said, ACK/NACK so we went in with this
initial splitting first.

Of course, because it made no sense at the time. Sam added it later with
his proposal patch.

have you even tried all those options and come up with concrete
suggestions on which options should go in and which shouldn't, and for
what reasons? I don't think so. So until you do, I don't care what you
have to say.

This is exactly why we're trying to get a feeling of this by _running_
it and _then_ _bitching_ about it. And this is for DEVELOPERS only - if
they've introduced it in their scripts, then they should be able to fix
any changes very easily.
