Help text

If you are doing generic system call fuzzing (like e.g. syzkaller), then you will want to instrument the whole kernel and you should say y here. If you are doing more targeted fuzzing (like e.g. filesystem fuzzing with AFL) then you will want to enable coverage for more specific subsets of files, and should say n here.
