arm64 regression bisected to "bpf: reject any prog that failed read-only lock"
From: dann frazier
Date: Fri Jun 22 2018 - 19:15:07 EST
fyi, I'm seeing a regression that I've bisected down to:
9facc336876f bpf: reject any prog that failed read-only lock
A snippet of the boot messages are below. I'll be out of pocket until
Monday, so apologies in advance for delays in responding to follow-ups.
