Hi YiFei.
This is OK for both trunk and GCC 10. Thanks for the fix! [I see you don't have a copyright transfer contract in place. I believe this change, and also the patch in 2/2, are small/trivial enough to not require one, but if you plan to do more contributions in the future we will need you to do the paperwork. I just sent you more information about this privately.] > Libbpf does not treat paddings after functions well.
