@jalajk24 Sure!

well, the eBPF's `exit` is not a proper example, according to the eBPF instruction set [docs](https://www.kernel.org/doc/html/latest/bpf/standardization/instruction-set.html#jump-instructions), the instruction `exit` refers to "return". but I still think it'll be great if...

oh, I think I need to figure out the calculation of return address before this change
