H A Dsched-design-CFS.rst36 在CFS中，虚拟运行时间由每个任务的p->se.vruntime（单位为纳秒）的值表达和跟踪。因此，
39 一些细节：在“理想的”硬件上，所有的任务在任何时刻都应该具有一样的p->se.vruntime值，
42 CFS的任务选择逻辑基于p->se.vruntime的值，因此非常简单：总是试图选择p->se.vruntime值
64 CFS维护了一个按时间排序的红黑树，所有可运行任务以p->se.vruntime为键值排序。CFS从这颗
70 p->se.vruntime。一旦p->se.vruntime变得足够大，其它的任务将成为按时间排序的红黑树的

H A Dsched-design-CFS.rst38 p->se.vruntime (nanosec-unit) value. This way, it's possible to accurately
42 p->se.vruntime value --- i.e., tasks would execute simultaneously and no task
45 CFS's task picking logic is based on this p->se.vruntime value and it is thus
46 very simple: it always tries to run the task with the smallest p->se.vruntime
66 increasing value tracking the smallest vruntime among all tasks in the
76 p->se.vruntime key. CFS picks the "leftmost" task from this tree and sticks to it.

54 La lógica de elección del tareas de CFS se basa en el valor de p->se.vruntime
