Remove buggy (root filesystems may not have cdev) and pointless

customization of an error message.

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

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.

Give kldunload a -f(orce) argument.

Add a MOD_QUIESCE event for modules. This should return error (EBUSY) of the module is in use. MOD_UNLOAD should now only fail if it is impossible (as opposed to inconvenient) to unload the module. Valid reasons are memory references into the module which cannot be tracked down and eliminated. When kldunloading, we abandon if MOD_UNLOAD fails, and if -force is not given, MOD_QUIESCE failing will also prevent the unload. For backwards compatibility, we treat EOPNOTSUPP from MOD_QUIESCE as success. Document that modules should return EOPNOTSUPP for unknown events.

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

Move dtrwait logic to the generic TTY level.

Define the tty methods as typedefs.

2004-06-30T21:38:08Z

Change the return type for t_break to void. Add t_ioctl (more about this later).

Use generic support for BREAK and modem control ioctls.

2004-06-25T10:54:05Z

Remove the TIOCDCDTIMESTAMP option.

The RFC-2783 PPS-API () provides better and more configurable service.

Put the pre FreeBSD-2.x tty compat code under BURN_BRIDGES.

Second half of the dev_t cleanup.

2004-06-17T17:16:53Z

The big lines are: NODEV -> NULL NOUDEV -> NODEV udev_t -> dev_t udev2dev() -> findcdev() Various minor adjustments including handling of userland access to kernel space struct cdev etc.
