函数名称：bpf_adj_linfo

函数原型：static void bpf_adj_linfo(struct bpf_prog *prog, u32 off, u32 delta)

返回类型：void

参数：

类型参数名称
struct bpf_prog *prog
u32off
u32delta
419  nr_linfo等于nr_linfo
420  如果非nr_linfo或非delta则返回
423  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.
425  以i小于nr_linfo循环如果off小于insn_off则
427  退出
430  以i小于nr_linfo循环insn_off加等于delta
