The alternative is to not worry about it and review the slow drip of fixes that will occur as a result. The issues I just fixed were built up over years. They won't get to that level again. In my mind contributors should be compiling their submissions with W=1 enabled by default. I'm fairly sure the auto-builders do this now. Once W=1 warnings are down to an acceptable level in the kernel as a whole, we can provide some guidance in SubmittingPatches (or similar) on how to enable them (hint: you add "W=1" on the compile line). Enabling W=1 in the default build will only serve to annoy Linus IMHO. If he wants them to be enabled by default, they wouldn't be W=1 in the first place, they'd be W=0 which *is* the default build. -- Lee Jones [李琼斯] Senior Technical Lead - Developer Services Linaro.org │ Open source software for Arm SoCs Follow Linaro: Facebook | Twitter | Blog
