类型参数名称
struct bpf_verifier_env *env
struct bpf_reg_state *regs
u32regno
1097  如果WARN_ON(regno >= BPF has 10 general purpose 64-bit registers and stack frame. )则
1098  verbose(env, "mark_reg_not_init(regs, %u)\n", regno)
1100  以regno小于BPF_REG_FP循环__mark_reg_not_init(env, regs + regno)
1102  返回
1104  __mark_reg_not_init(env, regs + regno)
