I had also compiled kernel with W=1, ran sparse and made sure that there aren't any warnings/errors with my changes. However, I didn't run smatch and coccicheck because I was facing difficulties in setting up these tools. I'll make sure that patches in future are scrutinized by all of these tools. > Best regards, > Krzysztof
