The test may fail if not enable DEBUG macro in dev_cgroup.c # ./test_dev_cgroup libbpf: load bpf program failed: Operation not permitted libbpf: failed to load program 'cgroup/dev' libbpf: failed to load object './dev_cgroup.o' Failed to load DEV_CGROUP program Removing the DEBUG macro makes the test always pass.
