+Subject: [PATCH 4/4] bugfix: check unsigned number flip before getting delta
+
+Sometimes, a very large number will appear in EXTxxx display items.
+The reason of this phenomenon is that we do not check the size of
+two unsigned numbers before getting delta value of them,
+which will cause unsigned number flip.
+So add check before getting delta value.

+Since the steal time, gtime, stime which are acquired from debugfs
