Description

Sometimes, we need to access rootFallBackLink in InodeTree from another package. One such case is we extend from ViewFileSystem but want to put the new filesystem in org.apache.hadoop.fs package, instead of org.apache.hadoop.fs.viewfs package. As a result, we need make them public, similar as what we did for getMountPoints() in HADOOP-18100.
