- * user-space. User-space application tend to expect that if the file-system
- * (e.g., via the 'statfs()' call) reports that it has N bytes available, they
- * are able to write a file of size N. UBIFS attaches node headers to each data
- * node and it has to write indexing nodes as well. This introduces additional
- * overhead, and UBIFS has to report slightly less free space to meet the above
- * expectations.
- *
- * This function assumes free space is made up of uncompressed data nodes and
- * full index nodes (one per data node, tripled because we always allow enough
- * space to write the index thrice).
- *
- * Note, the calculation is pessimistic, which means that most of the time
- * UBIFS reports less space than it actually has.

-	 * as less than maximum fanout, we assume that each data node
