Ok, i've cherry-picked it into urgent.
I'm wondering, how complete is the kprobes blacklist? You can test it by
putting a probe on every single function in the system via something like:
for N in $(cut -d' ' -f3 /proc/kallsyms | cut -f1); do
perf probe $N
perf probe -d $N
done
(note: I havent tested it myself yet.)
Thanks,
Ingo
