> Even though that is resolved as duplicate, the ID is actually not exposed by the JIRA it supposedly duplicates.
> INode ID for the file should be easy to expose; alternatively ID could be derived from block IDs, to account for appends...
> This is useful e.g. for cache key by file, to make sure cache stays correct when file is overwritten.
