2020-09-15selftests/bpf: Test load and dump metadata with btftool and skelYiFei Zhu1-0/+141
This is a simple test to check that loading and dumping metadata in btftool works, whether or not metadata contents are used by the program. A C test is also added to make sure the skeleton code can read the metadata values.
