tiny tty driver sample

Hello,

I'm trying to write a tty driver and I'm using
http://lwn.net/images/pdf/LDD3/ch18.pdf as a guide. The sample tiny tty
driver includes the following code:

for (i = 0; i < data_size; ++i) {
if (tty->flip.count >= TTY_FLIPBUF_SIZE)
tty_flip_buffer_push(tty);
tty_insert_flip_char(tty, data[i], TTY_NORMAL);
}
tty_flip_buffer_push(tty);

This doesn't compile against Linux 2.6.16 kernel I'm using, because
tty->flip.count doesn't exist anymore.
How should this sample be re-coded?

Thanks,

Jon
