I'm getting the following error when running 'gen skeleton -L' as regular user: libbpf: Error in bpf_object__probe_loading():Operation not permitted(1). Couldn't load trivial BPF program. Make sure your kernel supports BPF (CONFIG_BPF_SYSCALL=y) and/or that RLIMIT_MEMLOCK is set to big enough value. Fixes: 67234743736a ("libbpf: Generate loader program out of BPF ELF file.")
