Note, the ftrace_enabled becoming obsolete *can* be reverted if it breaks somebody's tool. So still be ready with this patch set. Also note, I have had success in getting changes that do break user space by fixing that user space so it's not broken again. But then I have to wait until all distros (including Debian Stable) have that version of the tool before I can add the change that broke it. -- Steve
