+Description:
+               It has three lines and shows the information about the
+               pseudo-link. The first line is a single number
+               representing a number of buckets. The second line is a
+               number of pseudo-links per buckets (separated by a
+               blank). The last line is a single number representing a
+               total number of psedo-links.
+               When the aufs mount option 'noplink' is specified, it
+               will show "1\n0\n0\n".
