+	* resize2fs.c (move_itables): Fix fencepost error caught by valgrind.
+		(adjust_superblock): Clear the newly allocated descriptor
+		blocks when we allocate them to avoid false positives from
+		valgrind (and so that the unusued descriptors at the tail
+		end of the newly allocated descriptor blocks are zero'ed
+		out, include of random garbage).
