 ** Changes in behavior

+  df no longer suppresses separate exports of the same remote device, as
+  these are generally explicitly mounted.  The --total option does still
+  suppress duplicate remote file systems.
+  [suppression was introduced in coreutils-8.21]

The remote mounts should not be suppressed after this change. However, 
it turns out

it doesn't work as the message described. The remote mounts are still 
suppressed. And here is

my patch for this problem:
