There is no reason why the "build > test" should be anything more than "make && echo yes i am build-tested". It damn well should check for warnings. And if you can't bother eye-balling it or scripting it, then simply use make KCFLAGS=-Werror but sadly I can't enforce that in general for all kernel builds simply because some people use compilers that cause new warnings (compiler updates etc commonly result in them, for example). So I can't add -Werror in general, but developers can certainly use it trivially. No grep or other scripting required (although the above may cause problems for that one sample file that does cause warnings - I didn't check). Linus
