放到 kprobe 后面吧:

放到ebpf.socket.sock_ops里krope后了

| 注意：该功能依赖 cgroup v2（统一层级）。在 cgroup v1 主机上 SockOps 绑定会失败。 | ||
|
|

| 限制：PID 跟踪依赖 `agent/src/ebpf/user/extended/bpf/tcp_option_tracing.bpf.c` 中的 per-CPU syscall map。当 CPU 拥堵或软中断在不同 CPU 上处理 TCP 时，注入的元数据可能缺失或过期。 |

相关文件以及前面的定义都在企业版中？

对的，不过这里可能不需要说明具体的路径？准备删掉这里路径文件名

定义在企业版中的话，那就需要把相关配置参数定义到extend-features中？不然开源版编译会有问题，有没有编译验证过？

github的编译测试应该不含企业版部分？看上去编译通过了
本地目前企业和开源部分放在一起，还没有单独测试

我说的是下图中添加的这部分，能确定开源版本单独编译没问题？

这里要说明内核版本要求，注意区分下 arm和x86 框架下的不同要求

目前arm只在高内核版本测试，之前的arm v2升级比较费劲
