-----------------------------------------------

Thanks, [~liuml07].  Does {{Long.valueOf(...)}} work?  It would be nice to avoid the typecast
if possible.

> Currently {{FileSystemStorageStatistics}} instance simply returns data from {{FileSystem$Statistics}}.
As to {{readOps}}, the {{FileSystem$Statistics#getReadOps()}} returns {{readOps + largeReadOps}}.
We should make the {{FileSystemStorageStatistics#getLong(“readOps“)}} return the sum as
well.
> Moreover, there is no unit tests for {{FileSystemStorageStatistics}} and this JIRA will
also address this.
