Sorry, I made a mistake here. ftrace_stack *does* use stack_trace under the hood, and so it can be easily modified to use the saved kretprobe stack. The only issue is with perf_callchain_entry (which affects bpf_get_stack). -- Aleksa Sarai Senior Software Engineer (Containers) SUSE Linux GmbH <https://www.cyphar.com/>
