Hi, lehui, thank you for your reply.
I noticed you patch mainly targeted on riscv64 and also extended support to other ARCH.
While these changes are to have not been merged into the mainline yet.
Becuse currently I want to use and extend BPF on Android.
So my focus is primarily on cross-compiling for arm64 on x86.
