bpf: Rename 'early' BTF checking as a preparation phase

2026-08-08T10:03:25+00:00

BTF processing is split around subprogram discovery. The first phase gets program BTF and imports func_info because a BTF-tagged exception callback may not be referenced by any instruction. Subprogram discovery needs this metadata to find it. The later phase validates func_info and line_info against the complete subprogram table and applies CO-RE relocations. This split breaks a real dependency cycle rather than merely running the same checks early. Rename bpf_check_btf_info_early() and check_btf_func_early() to preparation names that reflect this role. Add short call-site comments to make the two phases and their responsibilities clear. No functional change is intended.
