Don’t we normally say
	if (WARN_ON(&request->list == &ring->request_list))
		return -ENOSPC;
Yes, particularly since we've amended WARN_ON within i915 to print out
the condition that failed. "true" is not very useful with that. ;)

BR,
Jani.

The issue I have with 'if(WARN_ON(x))' is that it looks like something that would disappear in a non debugging build. Whereas, this is a check that wants to exist regardless of build options.
