This patch set implements an update to how BTF-defined maps are specified. The change is in how integer attributes, e.g., type, max_entries, map_flags, are specified: now they are captured as part of map definition struct's BTF type information (using array dimension), eliminating the need for compile-time data initialization and keeping all the metadata in one place. All existing selftests that were using BTF-defined maps are updated, along with some other selftests, that were switched to new syntax. v1->v2: - split bpf_helpers.h change from libbpf change (Song).
