Well, a simple patch which does

/*
 * comment goes here
 */
static inline int __must_check down_nowait(struct semaphore *sem)
{
	return !down_trylock(sem);
}

and which does not deprecate down_trylock() could go into mainline
right now, (assuming that the overall concept doesn't get shot down in
review - did it get reviewed?)

Then you can start trickling stuff out to people straight away.
