'RELENG_5_3_0_RELEASE'.

This commit was manufactured to restore the state of the 5.3-RELEASE image.

Preparation commit for the tty cleanups that will follow in the near

2004-07-15T20:47:41+00:00

future:

rename ttyopen() -> tty_open() and ttyclose() -> tty_close().

We need the ttyopen() and ttyclose() for the new generic cdevsw
functions for tty devices in order to have consistent naming.

Introduce ttygone() which indicates that the hardware is detached.

2004-07-11T15:18:39+00:00

Move dtrwait logic to the generic TTY level.

Define the tty methods as typedefs.

2004-06-30T21:38:08+00:00

Change the return type for t_break to void.

Add t_ioctl (more about this later).

Pick the hotchar out of the tty structure instead of caching private

2004-06-26T09:20:07+00:00

copies.

No current line disciplines have a dynamically changing hotchar, and
expecting to receive anything sensible during a change in ldisc is
insane so no locking of the hotchar field is necessary.

Use generic support for BREAK and modem control ioctls

2004-06-25T10:54:46+00:00

Do the dreaded s/dev_t/struct cdev */

2004-06-16T09:47:26+00:00

Bump __FreeBSD_version accordingly.

Centralize the line discipline optimization determination in a function

2004-06-04T21:55:55+00:00

called ttyldoptim().

Use this function from all the relevant drivers.

I belive no drivers finger linesw[] directly anymore, paving the way for
locking and refcounting.

Manual edits to change linesw[]-frobbing to ttyld_*() calls.

2004-06-04T20:04:52+00:00

Machine generated patch which changes linedisc calls from accessing

2004-06-04T16:02:56+00:00

linesw[] directly to using the ttyld...() functions

The ttyld...() functions ar inline so there is no performance hit.
