But what if a TTY driver uses the tty_schedule_flip() function instead of tty_flip_buffer_push() and has low_latency set to 1? In that case the work queue will never be flushed... Or should drivers that use tty_schedule_flip() function never set the low_latency flag? (a quick scan indeed shows that all drivers that use the low_latency flag indeed make use of the tty_flip_buffer_push() function).
