perf lock contention returns zero exit value even if the lock contention BPF setup failed. # ./perf lock con -b true libbpf: kernel BTF is missing at '/sys/kernel/btf/vmlinux', was CONFIG_DEBUG_INFO_BTF enabled? libbpf: failed to find '.BTF' ELF section in /lib/modules/6.13.0-rc3+/build/vmlinux libbpf: failed to find valid kernel BTF libbpf: kernel BTF is missing at '/sys/kernel/btf/vmlinux', was CONFIG_DEBUG_INFO_BTF enabled? libbpf: failed to find '.BTF' ELF section in /lib/modules/6.13.0-rc3+/build/vmlinux libbpf: failed to find valid kernel BTF libbpf: Error loading vmlinux BTF: -ESRCH libbpf: failed to load object 'lock_contention_bpf' libbpf: failed to load BPF skeleton 'lock_contention_bpf': -ESRCH Failed to load lock-contention BPF skeleton lock contention BPF setup failed # echo $? 0 Fix this by saving the return code for lock_contention_prepare so that command exits with proper return code. Similarly set the return code properly for two other functions in builtin-lock, namely setup_output_field() and select_key().
