The Static Check Needle in the Warnings Haystack - Frank Rowand, Sony

The messages from the various static check tools can be overwhelming. When you make a minor change to a Linux kernel source file, the number of warnings may change slightly but it may be difficult to find the few new warnings in the large pile of all warnings, or the number of warning may remain the same but it may be difficult to determine that the warnings did not change. Tools and techiques will be presented to help you more quickly and easily determine whether your patch has created a new problem. And if new problems exist, how to determine what the problem is. This information will help you submit cleaner patches. In my dreams for a better world, these tools and techniques may also aid in reducing the current backlog of static check warnings present in the kernel code.
