Similar to other btf_decl_tag cases, func/func_param/global_var/struct/union/field, btf_decl_tag with typedef declaration can carry information from kernel source to clang compiler and then to dwarf/BTF, for bpf verification or other use cases. This patch set added kernel support for BTF_KIND_DECL_TAG to typedef declaration (Patch 1). Additional selftests are added to cover unit testing, dedup, or bpf program usage of btf_decl_tag with typedef. (Patches 2, 3 and 4). The btf documentation is updated to include BTF_KIND_DECL_TAG typedef (Patch 5).
