struct iattr *iattr
3092  cred等于current_cred - Access the current task's subjective credentials* Access the subjective credentials of the current task. RCU-safe,* since nobody else can modify it.()
3093  inode等于d_backing_inode - Get upper or lower inode we should be using*@upper: The upper layer* This is the helper that should be used to get at the inode that will be used* if this dentry were to be opened as a file. The inode may be on the upper
