it could be a silly question, but better to ask...

Would this also work for task == current? Given that the original code had
> - start_backtrace(&frame,
> - (unsigned long)__builtin_frame_address(0),
> - (unsigned long)__save_stack_trace);
for the case, which seems correct (but I don't know much about arm64 arch
in the kernel).
Otherwise, I did not spot anything suspicious or wrong.
