		bool	lazy,
		bool	fifo_idle,
		uint32_t	seqno,
		bool	interruptible,
		unsigned long	timeout
	)

Block command submission while waiting for idle.

FIXME: Use schedule_hr_timeout here for newer kernels and lower CPU utilization.

	)

Then check if the seqno is higher than what we've actually emitted. Then the fence is stale and signaled.
