After that the following will be changing - tty->driver will no longer contain a copy of all the operations methods but that will become tty->driver->ops and in turn tty->ops - Helpers will appear for things like write_room/put_char/chars_in_buffer These will be mandatory to use so that we can stamp out all the corner cases where some combinations of ldisc/driver crash the box due to bogus assumptions about what methods must be present. - break_ctl will become mandatory for break handling removing all the duplicated per driver cruft in old drivers. - put_char methods will return 0/1 if they queued the character.
