函数名称：bpf_fill_maxinsns3

函数原型：static int bpf_fill_maxinsns3(struct bpf_test *self)

返回类型：int

参数：

类型参数名称
struct bpf_test *self
128  len等于BPF_MAXINSNS
133  insn等于分配数组内存
134  如果非insn则返回:负ENOMEM
137  prandom_seed_state - set seed for prandom_u32_state().*@state: pointer to state structure to receive the seed.*@seed: arbitrary 64-bit value to use as a seed.
139  以i小于len减1循环
140  k等于prandom_u32_state( & rnd)
142  insn[i]等于Internal classic blocks for direct assignment (BPF_ALU | BPF_ADD | BPF_K, k)
145  insn[len - 1]等于Internal classic blocks for direct assignment (BPF_RET | BPF_A, 0)
147  insns等于insn
148  len等于len
150  返回:0
