Great, at least we know the kernel is probably good (assuming Linux gets tested too and at least the latest version doesn't have bugs)... But I still worry about the interactions in a complex userspace application can produce unexpected outcomes. And I wonder whether Linux previously had bugs (too lazy to trace down the git history today), and if there was, how many are still in deployment...
