TTY_FLIPBUF_SIZE is going away. Just pick a value good for your hardware
and under PAGE_SIZE.
Thanks for your comments. I'll change it soon and submit a new patch.
Other question - is your locking ok for low latency. In low latency mode
tty_flip_buffer_push() may directly end up calling your write methods.
Yes, I noticed that and I think it's ok. The driver is tested everday
and works fine.
