I remember now. I didn't add it because the update_ftrace_function was
too much at the time. It was still doing the basic updates, but it was
also doing a bit more too. But this was before I added the extra checks.
I didn't call it because it seemed to be an overkill. But that doesn't
apply today.

OK, I'll add it and it looks like it needs to go immediately, as well as
way back to 3.0 stable.

Thanks!
