Hi!

Do we really want developers treat warnings as errors? When the code is okay but some random version of gcc dislikes it... Plus, there's question of stable. We already get ton of churn there ("this fixes random warning"). WERROR will only encourage that...I will not be backporting this patch to older stable kernels, but I _want_ to see stable builds build with no warnings. When we add warnings, they are almost always things we need to fix up properly.
Well, everyone _wants_ to see clean builds... unless the price is too high.
Over time, I have worked to reduce the number of build warnings in older stable kernels. For newer versions of gcc, sometimes that is impossible, but we are close...
You clearly can't backport this patch, but for 5.16-stable, you'll have it in, and now warnings are same as errors... and I don't believe that's good idea for stable. Best regards, Pavel -- http://www.livejournal.com/~pavelmachek
