Kumar Kartikeya Dwivedi edc3ec09ab bpf: Factor out fd returning from bpf_btf_find_by_name_kind ... In next few patches, we need a helper that searches all kernel BTFs (vmlinux and module BTFs), and finds the type denoted by 'name' and 'kind'. Turns out bpf_btf_find_by_name_kind already does the same thing, but it instead returns a BTF ID and optionally fd (if module BTF). This is used for relocating ksyms in BPF loader code (bpftool gen skel -L). We extract the core code out into a new helper bpf_find_btf_id, which returns the BTF ID in the return value, and BTF pointer in an out parameter. The reference for the returned BTF pointer is always raised, hence user must either transfer it (e.g. to a fd), or release it after use.
