kdb_task_state

函数名称：kdb_task_state_char - Return the character that represents the task state.* Inputs:* p struct task for the process* Returns:* One character to represent the task state.

函数原型：char kdb_task_state_char(const struct task_struct *p)

返回类型：char

参数：

类型	参数	名称
const struct task_struct *	p

如果非p或probe_kernel_read(): safely attempt to read from a location*@dst: pointer to the buffer that shall take the data*@src: address to read from*@size: size of the data chunk* Safely read from address @src to the buffer at @dst. If a kernel fault则返回:'E'

630

cpu等于kdb_process_cpu(p)

631

state等于如果如果如果如果如果如果如果如果任务状态恒等于0则'R'否则任务状态小于0则'U'否则任务状态按位与深度睡眠态则'D'否则任务状态按位与TASK_STOPPED则'T'否则任务状态按位与TASK_TRACED则'C'否则进程退出时状态按位与EXIT_ZOMBIE则'Z'否则进程退出时状态按位与Used in tsk->exit_state: 则'E'否则任务状态按位与睡眠态则'S'否则'?'

639

如果是空闲任务则

642

如果非kdb_task_has_cpu(p)或irq_depth恒等于1则

643

如果cpu不等于cpu number that owns kdb 则state等于'I'

646

否则如果非内存信息且state恒等于'S'则

647

state等于'M'

649

返回:state
