 * RBD: The output of `rbd snap ls --all` command now includes the original
   type for trashed snapshots.
+* CephFS: "ceph fs clone status" command will now print statistics about clone
+  progress in terms of how much data has been cloned (in both percentage as
+  well as bytes) and how many files have been cloned.
+* CephFS: "ceph status" command will now print a progress bar when cloning is
+  ongoing. If clone jobs are more than the cloner threads, it will print one
+  more progress bar that shows total amount of progress made by both ongoing
+  as well as pending clones. Both progress are accompanied by messages that
+  show number of clone jobs in the respective categories and the amount of
+  progress made by each of them.

+A progress report is also printed in the output when clone is ``in-progress``.

+progress made by all ongoing clones, a progress bar is printed at the bottom
+in ouput of ``ceph status`` command::
+
+  progress:
+    3 ongoing clones - average progress is 47.569% (10s)

+If the number of clone jobs are more than cloner threads, two progress bars
