参数：

类型参数名称
struct tomoyo_obj_info *obj
716  struct dentry * dentry = NULL
718  以i小于TOMOYO_MAX_PATH_STAT循环
722  当:i恒等于TOMOYO_PATH1
723  dentry等于dentry
724  如果非dentry则继续下一循环
726  退出
727  当:i恒等于TOMOYO_PATH2
728  dentry等于dentry
729  如果非dentry则继续下一循环
731  退出
732  默认
733  如果非dentry则继续下一循环
735  dentry等于dget_parent(dentry)
736  退出
738  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
739  如果inode则
740  stat等于* Information on @path1, @path1's parent directory, @path2, @path2's * parent directory.[i]
742  uid等于i_uid
743  gid等于i_gid
744  ino等于Stat data, not accessed from path walking
745  mode等于i_mode
746  dev等于s_dev
747  rdev等于i_rdev
748  True if @stat[] is valid. [i] = true
750  如果i按位与1则dput(dentry)
