Hi,

I encountered this splat with 4.12-RC2.

Ugh, yeah, I should've seen that in the review.

Arend, please take a look at this. cfg80211_sched_scan_results() cannot
sleep, so you can't rtnl_lock() in there. Looks like you can just rely
on RCU though?

I see. I think you are right on RCU. Don't have the code in front of me 
now, but I think the lookup has an ASSERT_RTNL. Will look into it after 
my monday meeting :-p

Regards,
Arend
