[PATCH v6 tip 5/8] samples: bpf: simple non-portable kprobe filter example

tracex1_kern.c - C program compiled into BPF. It attaches to kprobe:netif_receive_skb When skb->dev->name == "lo", it prints sample debug message into trace_pipe via bpf_trace_printk() helper function. tracex1_user.c - corresponding user space component that: - loads bpf program via bpf() syscall
