------------------------------
+1, thanks Jing.
I check the patch, now if {{getContentSummary}} on snapshot path, only content
in snapshot is counted.
> Correctly handle snapshot path for getContentSummary

> The current getContentSummary implementation does not take into account the
> snapshot path, thus if we have the following ops:
> 1. create dirs /foo/bar
> 2. take snapshot s1 on /foo
> 3. create a 1 byte file /foo/bar/baz
> then "du /foo" and "du /foo/.snapshot/s1" can report same results for "bar",
> which is incorrect since the 1 byte file is not included in snapshot s1.
