Jiri Olsa db8eae6bc5 bpf: Force kprobe multi expected_attach_type for kprobe_multi link ... We currently allow to create perf link for program with expected_attach_type == BPF_TRACE_KPROBE_MULTI. This will cause crash when we call helpers like get_attach_cookie or get_func_ip in such program, because it will call the kprobe_multi's version (current->bpf_ctx context setup) of those helpers while it expects perf_link's current->bpf_ctx context setup. Making sure that we use BPF_TRACE_KPROBE_MULTI expected_attach_type only for programs attaching through kprobe_multi link.
