【Linux】进程概念 —— 进程状态_linux d状态进程_Hello_World_213的博客-CSDN博客

新建：字面意思，将你的task_struct创建出来并且还未入队列

运行：task_struct结构体在运行队列中排队，就叫做运行态

阻塞： 等待非CPU资源就绪，阻塞状态

 

挂起：当内存不足的时候，OS通过适当的置换进程的代码和数据到磁盘，进程的状态就叫做挂起！

进程状态在Linux内核中的源代码：

/*
* The task state array is a strange "bitmap" of
* reasons to sleep. Thus "running" is zero, and
* you can test for combinations of others with
* simple bit tests.
*/
static const char * const task_state_array[] = {
"R (running)", /* 0 */
"S (sleeping)", /* 1 */
"D (disk sleep)", /* 2 */
"T (stopped)", /* 4 */
"t (tracing stop)", /* 8 */
"X (dead)", /* 16 */
"Z (zombie)", /* 32 */
};
