+
+  SYNOPSIS
+    check_reorganise_list()
+    new_part_info      New partition info
+    old_part_info      Old partition info
+    list_part_names    The list of partition names that will go away and
+                       can be reused in the new table.
+
+  RETURN VALUES
+    TRUE               Inacceptable name conflict detected.
+    FALSE              New names are OK.
+
+  DESCRIPTION
+    Can handle that the 'new_part_info' and 'old_part_info' the same
+    in which case it checks that the list of names in the partitions
+    doesn't contain any duplicated names.
