函数名称：find_linfo

函数原型：static const struct bpf_line_info *find_linfo(const struct bpf_verifier_env *env, u32 insn_off)

返回类型：struct bpf_line_info

参数：

类型参数名称
const struct bpf_verifier_env *env
u32insn_off
248  prog等于BPF program being verified
249  nr_linfo等于nr_linfo
251  如果非nr_linfo或insn_off大于等于 Number of filter blocks 则返回:NULL
254  linfo等于 bpf_line_info loaded from userspace. linfo->insn_off * has the xlated insn offset. * Both the main and sub prog share the same linfo. * The subprog can access its first linfo by * using the linfo_idx.
255  以i小于nr_linfo循环如果insn_off小于insn_off则
257  退出
259  返回:linfo[i - 1]
