It has two already.

I wouldn't worry about being shaky about the lifetime rules, thats a
forensics job at the moment.

Sensible way to go whichever path we use and once it returns a refcount

just current_tty() would fit the naming in the kernel better


I agree entirely with the path this patch is taking.
