Thanks for all the comments! I am updating the code following your suggestions.
Next step will be to split this into three distinct patches, as suggested by Pavel.

Fixed, but I see the -*- C++ -*- in all files.

But all the C++ files seem to have "-*- C++ -*-===//" in the first line.

Yes, it was edited by clang format.

   EM_BPF = 247,           // Linux kernel bpf virtual machine
