- * wait_event_interruptible_tty -- wait for a condition with the tty lock held
- *
- * The condition we are waiting for might take a long time to
- * become true, or might depend on another thread taking the
- * BTM. In either case, we need to drop the BTM to guarantee
- * forward progress. This is a leftover from the conversion
