27 也就是传统的Unix进程。尽管使用了tgid这个词，即使一个任务是线程组组长，
35 （NETLINK_GENERIC族）然后发送指定pid或tgid的命令。响应消息中包含单个
36 任务的统计信息（若指定了pid）或进程所有任务汇总的统计信息（若指定了tgid）。
43 如果正在退出的任务是线程组中最后一个退出的线程，额外一条包含每tgid统计信息的
48 用户可注册cpu掩码、发送命令和处理响应、监听每tid/tgid退出数据、将收到的数据
59 struct taskstats是每pid和每tgid数据共用的计数结构体。它是版本化的，可在内核新增
71 1. 命令：由用户发送给内核。获取指定pid/tgid数据的命令包含一个类型为
72 TASKSTATS_CMD_ATTR_PID/TGID的属性，该属性包含u32的pid或tgid载荷。
73 pid/tgid指示用户空间要统计的任务/进程。
