H A Dcredentials.rst213 在Linux中，一个任务的所有凭据都保存在一个引用计数结构体‘struct cred’中，
215 task_struct中通过一个名为‘cred’的指针指向其凭据。
232 要更改cred结构体中的任何内容，必须遵循复制和替换的原则。首先进行复制，然后修
264 const struct cred *current_cred()
290 const struct cred *get_current_cred(void);

331 const struct cred *get_task_cred(struct task_struct *task);
