 *
 * a) number of the node's first cluster

 *    within the parent directory
 *
 * We need VFS indices to be:
 * A) unique
 * B) stable in time, at least until the next mount
 *
 * Unfortunately a) does not meet the A) criterion because zero-length files
 * will have the first cluster field cleared.  And b) does not meet the B)
 * criterion because unlink() and rename() will both free up the original
 * dentry, which contains all the essential info about the file.
 *
 * Therefore, a completely opaque indices are used and the FAT server maintains
 * a mapping between them and otherwise nice b) variant.  On rename(), the VFS
 * index stays unaltered, while the internal FAT "physical tree address"
 * changes.  The unlink case is also handled this way thanks to an in-core node
