[PATCH] D93563: BPF: add extern func to data sections if specified

[Alexei Starovoitov via Phabricator via llvm-commits]

ast added a comment.

why the current behavior is not enough?
BTF_KIND_FUNC (foo1) -> BTF_KIND_FUNC_PROTO (foo1)
BTF_KIND_FUNC (foo2) -> BTF_KIND_FUNC_PROTO (foo2)
libbpf can use order to find proper function. foo can be extern as it is right now. Then libbpf will first try to match between multiple elf bpf files. If still not found it will search in vmlinux/mods.
I think using KIND_VAR is incorrect. There is no variable here.
