This implementation is very similar to stack_trace_save_tsk(), maybe we

No, we want to move away from the stack_trace_*() API because it has
very unclear semantics and various arch implementations differ in
details.
There's a patch that untangles arch_stack_walk*() from CONFIG_STACKTRACE
and we can eventually use that.
Got it.
