@ -20,6 +20,9 @@ current_tracer. Instead of that, add probe points via
/sys/kernel/debug/tracing/kprobe_events, and enable it via
/sys/kernel/debug/tracing/events/kprobes/<EVENT>/enable.
You can also use /sys/kernel/debug/tracing/dynamic_events instead of
kprobe_events. That interface will provide unified access to other
dynamic events too.
