2021-10-01selftests/bpf: Use BTF-defined key/value for map definitionsHengqi Chen
Change map definitions in BPF selftests to use BTF-defined key/value types. This unifies the map definitions and ensures libbpf won't emit warning about retrying map creation.

2021-07-19selftests/bpf: Check inner map deletionMartynas Pumputis
Add a test case to check whether an unsuccessful creation of an outer map of a BTF-defined map-in-map destroys the inner map. As bpf_object__create_map() is a static function, we cannot just call it from the test case and then check whether a map accessible via map->inner_map_fd has been closed. Instead, we iterate over all maps and check whether the map "$MAP_NAME.inner" does not exist.
