在Linuxkernel中，所有的进程都是用双链表表示的，双链表带的数据是task_struct. kernel保存一个current指针，指向当前系统中执行的进程。

Within the Linux kernel, all active processes are represented using a doubly linked list of task_struct. The kernel maintains a pointer-current-to the process currently executing on the system.

对于每个可能的顺序表表示法，您都会需要一个光标的表示法。一个数组，一个链表和一个文件是表示法的三个例子。

For each possible sequential table representation you will need a representation for the cursor. Three example representations are by an array, a linked list and a file.
