函数名称：bpf_fill_maxinsns9

函数原型：static int bpf_fill_maxinsns9(struct bpf_test *self)

返回类型：int

参数：

类型参数名称
struct bpf_test *self
268  len等于BPF_MAXINSNS
272  insn等于分配数组内存
273  如果非insn则返回:负ENOMEM
276  insn[0]等于Conditional jumps against immediates, if (dst_reg 'op' imm32) goto pc + off16 (BPF_JA, 0, 0, len - 2)
277  insn[1]等于BPF_ALU32_IMM(mov reg to reg , Redefine REGs to make tests less verbose , 0xcbababab)
278  insn[2]等于Program exit ()
280  以i小于len减2循环insn[i]等于BPF_ALU32_IMM(mov reg to reg , Redefine REGs to make tests less verbose , 0xfefefefe)
283  insn[len - 2]等于Program exit ()
284  insn[len - 1]等于Conditional jumps against immediates, if (dst_reg 'op' imm32) goto pc + off16 (BPF_JA, 0, 0, - (len - 1))
286  insns等于insn
287  len等于len
289  返回:0
