If it's true that there are too many false positives like 95%, then I'll fix those fist for sure before asking to merge it. Let's see if so. To kernel developers, It'd be appreciated if you'd let us know if you can see real ones than false positives in the middle of developing something in the kernel so it's useful. Otherwise, it's hard to measure how many false positives it reports and how valuable it is and so on... Thanks, Byungchul
