But rather than maintain the tasks in a run queue, as has been done in prior Linux schedulers, the CFS maintains a time-ordered red-black tree (see Figure 1).
但是与之前的Linux调度器不同，它没有将任务维护在运行队列中，CFS维护了一个以时间为顺序的红黑树(参见图1)。
The red-black tree is O(log n) in time for most operations, while the previous scheduler employed O(1), using a priority array with a fixed number of priorities.
对于大多数操作，红黑树的执行时间为O(logn)，而以前的调度程序通过具有固定优先级的优先级数组使用 O(1)。
The data structure used is a red-black tree, which is ideal for performance-focused applications (and happens to be available generically as a library within the kernel).
这个数据结构是一个“红-黑”树，对于注重性能的应用程序很理想(且恰好作为内核中的一个库普遍可用)。
The first potential future change would modify the unacknowledged packet list so that it is organized with an index as a red-black tree instead of the current linear list.
第一个可能的未来改变是对未应答的包列表进行修改，因此包列表的组织形式不再是当前的线性列表而是通过索引组织成红-黑树。
Most importantly, the sched_entity contains the vruntime (64-bit field), which indicates the amount of time the task has run and serves as the index for the red-black tree.
最重要的是， sched_entity包含vruntime（64位字段），它表示任务运行的时间量，并作为红黑树的索引。
Dequeue_task: When a task is no longer runnable, this function is called to keep the corresponding scheduling entity out of the red-black tree. It decrements the nr_running variable.
dequeue _ task：当某个任务退出可运行状态时调用该函数，它将从红黑树中去掉对应的调度实体，并从nr_running变量中减1。
