How often are new W=1 flags added? My patch exported
KBUILD_CFLAGS_WARN1. How about instead we export
KBUILD_CFLAGS_WARN1_20200920. A subsystem can then sign up to being
W=1 clean as for the 20200920 definition of W=1.

I think this is a reasonable idea.

I'm hitting exactly the issue this series is trying to solve, Lee
invested a lot of effort to make drivers/infiniband/ W=1 clean, but
as maintainer I can't sustain this since there is no easy way to have
a warning free compile and get all extra warnings.  Also all my
submitters are not running with W=1

I need kbuild to get everyone on the same page to be able to sustain
the warning clean up. We've already had a regression and it has only
been a few weeks :(

Andrew, would you consider respinning this series in the above form?

Arnd has worked on the core parts. But i lost track of if his patches
got merged.
