Description

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.
