Looking at the function again, shouldn't we add !rb_is_static(cpu_buffer) as
well to the full page test?  

Why?

So that the splice can make progress when the ring-buffer is presistent or
user-mapped. Or do we say that's expected behaviour? 

Ah yeah, I see. Hmm, looking at the code to see how this would work, I
think I found another bug. Let me look deeper into it.
