pty: simplify unix98 allocation

2008-10-13T16:51:44+00:00

We need both termios and termios_locked so allocate them as one

pty: Fix allocation failure double free

2008-10-13T16:51:44+00:00

The updating and moving around of the pty code added a bug where both the
helper and caller free the main tty struct (the pty driver must free the
o_tty pair itself however).

pty: Coding style and polish

2008-10-13T16:51:43+00:00

We've done the heavy lifting now its time to mop up a bit

Add an instance parameter devpts interfaces

2008-10-13T16:51:43+00:00

Pass-in 'inode' or 'tty' parameter to devpts interfaces.  With multiple
devpts instances, these parameters will be used in subsequent patches
to identify the instance of devpts mounted. The parameters also help
simplify devpts implementation.

Changelog[v3]:
	- minor changes due to merge with ttydev updates
	- rename parameters to emphasize they are ptmx or pts inodes
	- pass-in tty_struct * to devpts_pty_kill() (this will help
	  cleanup the get_node() call in a subsequent patch)

tty: extract the pty init time special cases

2008-10-13T16:51:43+00:00

The majority of the remaining init_dev code is pty special cases. We
refactor this code into the driver->install method.

tty: Finish fixing up the init_dev interface to use ERR_PTR

2008-10-13T16:51:43+00:00

Original suggestion and proposal from Sukadev Bhattiprolu.

tty: More driver operations

2008-10-13T16:51:42+00:00

We have the lookup operation abstracted which is nice for pty cleanup but
we really want to abstract the add/remove entries as well so that we can
pull the pty code out of the tty core and create a clear defined interface
for the tty driver table.

Fix up the naming, style and extract some bits of code into the driver

tty: Remove more special casing and out of place code

2008-10-13T16:51:42+00:00

Carry on pushing code out of tty_io when it belongs to other drivers. I'm
not 100% happy with some of this and it will be worth revisiting some of the
exports later when the restructuring work is done.
