It may be worthwhile calculating how many indirect blocks there actually
are in a file that size.
The math become more confusing for that right ?. I am not sure we need to be that specific.
Also note that your comments are backward -
there is at most a single triple indirect block per file.
What i meant by those comment was, the count of meta data blocks taken for
different type of indirect blocks.
