What are the implications of that? /** * tty_flip_buffer_push - terminal * @tty: tty to push * * Queue a push of the terminal flip buffers to the line discipline. This * function must not be called from IRQ context if tty->low_latency is set. Apparently we cannot. Possibly throtteling has to set in earlier. Increasing the buffer's size wouldn't work either, as we'd hit kmalloc's limit.
