Subject: Serial Roadmap
Date: Thu, 27 Mar 2008 16:10:06 +0000	[thread overview]
Message-ID: <20080327161006.2db03b5a@core> (raw)

Basic lock_kernel free serial is now pushed to the -mm tree, with a few
more lock drops to get pushed but tested.

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.
