H A Dtaskstats.rst3 :Original: Documentation/accounting/taskstats.rst
47 getdelays.c是一个简单的示例，用以演示如何使用taskstats接口获取延迟统计信息。
54 内核用户接口封装在include/linux/taskstats.h。
56 为避免本文档随着接口的演进而过期，本文仅给出当前版本的概要。当本文与taskstats.h
57 不一致时，以taskstats.h为准。
60 计数子系统时进行扩展。taskstats.h中定义了各字段及语义。
104 除了每任务的统计信息，taskstats还提供每进程的统计信息，因为资源管理通常以进程
108 为解决此问题，taskstats代码将退出任务的统计信息累积到进程范围的数据结构中。
114 扩展taskstats
117 有两种方法可在未来修改内核扩展taskstats接口，以导出更多的每任务/进程统计信息：
