Thanks, but ... I was going to send another revision.

See: https://lkml.org/lkml/2016/3/11/721

There were a couple of items I wanted to fix.

   1) Missing MODULE_LICENSE() in new common code source file results in 
taint warnings.

   2) Fix device reference counts for -EPROBE_DEFER case.


At this point, I think the best path forward is for me to rebase against 
net-next and send you a small fixup set to what was merged.

What do you think?
