Thanks for all the replies.  I'm running bluez on a raspberry pi 2 and
as far as I can tell, there isn't an easy path to a 4.1 kernel.  I
applied all the updates to my installation and ended up at 4.07.  I
don't have a lot of linux background, but from googling the topic, it
seems like 4.1 is so new that it isn't universally available.
