this function. In such a situation defer it.
+Driver Access
+
+Line discipline methods can call the following methods of the underlying
+hardware driver through the function pointers within the tty->driver
+structure:
+
+write() Write a block of characters to the tty device.
+ Returns the number of characters accepted.
+
+put_char() Queues a character for writing to the tty device.
+ If there is no room in the queue, the character is
+ ignored.
+
+flush_chars() (Optional) If defined, must be called after
+ queueing characters with put_char() in order to
+ start transmission.
+
+write_room() Returns the numbers of characters the tty driver
+ will accept for queueing to be written.
+
+ioctl() Invoke device specific ioctl.
+ Expects data pointers to refer to userspace.
+ Returns ENOIOCTLCMD for unrecognized ioctl numbers.
+
+set_termios() Notify the tty driver that the device's termios
+ settings have changed. New settings are in
+ tty->termios. Previous settings should be passed in
+ the "old" argument.
+
+throttle() Notify the tty driver that input buffers for the
+ line discipline are close to full, and it should
+ somehow signal that no more characters should be
+ sent to the tty.
+
+unthrottle() Notify the tty driver that characters can now be
+ sent to the tty without fear of overrunning the
+ input buffers of the line disciplines.
+
+stop() Ask the tty driver to stop outputting characters
+ to the tty device.
+
+start() Ask the tty driver to resume sending characters
+ to the tty device.
+
+hangup() Ask the tty driver to hang up the tty device.
+
+break_ctl() (Optional) Ask the tty driver to turn on or off
+ BREAK status on the RS-232 port. If state is -1,
+ then the BREAK status should be turned on; if
+ state is 0, then BREAK should be turned off.
+ If this routine is not implemented, use ioctls
+ TIOCSBRK / TIOCCBRK instead.
+
+wait_until_sent() Waits until the device has written out all of the
+ characters in its transmitter FIFO.
+
+send_xchar() Send a high-priority XON/XOFF character to the device.
+
+
+Flags
+
+Line discipline methods have access to tty->flags field containing the
+following interesting flags:
+
+TTY_THROTTLED Driver input is throttled. The ldisc should call
+ tty->driver->unthrottle() in order to resume
+ reception when it is ready to process more data.
+
+TTY_DO_WRITE_WAKEUP If set, causes the driver to call the ldisc's
+ write_wakeup() method in order to resume
+ transmission when it can accept more data
+ to transmit.
+
+TTY_IO_ERROR If set, causes all subsequent userspace read/write
+ calls on the tty to fail, returning -EIO.
+
+TTY_OTHER_CLOSED Device is a pty and the other side has closed.
+
+TTY_NO_WRITE_SPLIT Prevent driver from splitting up writes into
+ smaller chunks.
+
+

Callers to the line discipline functions from the tty layer are required to
