Unable to get the function offset of sched_blocked_reason using Perfetto

Hello, when I use Pertetto to capture the trace, the caller of sched_blocked_reason is just a function name without offset. Like this:


But it can be displayed normally when I grab ftrace alone. Do you know how to solve it?
```
echo 1 >/sys/kernel/tracing/events/sched/sched_blocked_reason/enable

echo 1 > /sys/kernel/tracing/tracing_on

cat /sys/kernel/tracing/trace
```
