It's specifically looking for code like "(foo + bar < foo)" where the addition operation is signed. Could you CC me on the fixes, just for reference and maybe I can check for those as well. regards, dan carpenter -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
