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.)
