inode_find:  Now takes struct inode_desc_s type as input.  This was necessary before that structure includes some data storage.  It was used within inode_find(), but that means that the life of the data was the life of inode_find().  That data must persist longer.  It is now provided by the caller so that the life of the data persists for the entire life of the caller.
