H A Dtaskstats.rst26 “tgid”、“进程”、“线程组”互换使用，用于描述共享mm_struct的任务集，
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。

H A Ddelay-accounting.rst40 向用户态返回一个通用数据结构，对应每pid或每tgid的统计信息。延时计数功能填写
51 若其为线程组最后一个退出的任务，内核还会发送每tgid的统计信息。更多详细信息见
74 系统启动后，使用类似getdelays.c的工具获取任务或线程组（tgid）的延时信息。
78 getdelays [-dilv] [-t tgid] [-p pid]

H A Dtaskstats.rst22 "tgid", "process" and "thread group" are used interchangeably and refer to the
24 use of tgid, there is no special treatment for the task that is thread group
31 socket (NETLINK_GENERIC family) and sends commands specifying a pid or a tgid.
33 statistics for all tasks of the process (if tgid is specified).
43 an additional record containing the per-tgid stats is also sent to userspace.
49 send commands and process responses, listen for per-tid/tgid exit data,
63 per-tgid data. It is versioned and can be extended by each accounting subsystem
79 a pid/tgid consist of one attribute, of type TASKSTATS_CMD_ATTR_PID/TGID,
80 containing a u32 pid or tgid in the attribute payload. The pid/tgid denotes
97 indicates a pid/tgid will be followed by some stats.
