Emit the bpf_kfunc decl tag for every discovered kfunc, and bpf_fastcall for kfuncs flagged KF_FASTCALL. These were previously produced by pahole under --btf_features=decl_tag_kfuncs. resolve_btfids now discovers kfuncs from the BTF ID sets [1] and becomes the source of truth for their annotations. Drop decl_tag_kfuncs pahole feature flag from scripts/Makefile.btf [1] https://lore.kernel.org/all/20260722233518.778854-1-ihor.solodrai@linux.dev/ Signed-off-by: Ihor Solodrai <ihor.solodrai@linux.dev> Acked-by: Eduard Zingerman <eddyz87@gmail.com> Link: https://patch.msgid.link/20260807032029.78092-5-ihor.solodrai@linux.dev Signed-off-by: Eduard Zingerman <eddyz87@gmail.com>
