You can create a tty_struct kernel side with the two tiny changes I
posted before. Why do you want to do invasive tree wide changes when you
can do simple ones ?

I think before this lot happens you need to decide where these structures
belong. Termios and termios_locked for example could live in the tty_port
as the physical tty is incapable of having multiple sets of terminal data
at once.

Really though this looks to me like *MASSIVE* churn for now purpose.
Create a tty_struct kernel side, and use that, the needed patch is then
