| parent | libbpf: Switch tracing and CO-RE helper macros to bpf_probe_read_kernel() (diff) | |
libbpf: Detect minimal BTF support and skip BTF loading, if missing
Detect whether a kernel supports any BTF at all, and if not, don't even
attempt loading BTF to avoid unnecessary log messages like:
libbpf: Error loading BTF: Invalid argument(22)
libbpf: Error loading .BTF into kernel: -22. BTF is optional, ignoring.
