* 10/04/98 dgb Added rudimentary directory functions
* 10/07/98 Fully working udf_block_map! It works!
* 11/25/98 bmap altered to better support extents
- * 12/06/98 blf partition support in udf_iget, udf_block_map and udf_read_inode
+ * 12/06/98 blf partition support in udf_iget, udf_block_map
+ * and udf_read_inode
* 12/12/98 rewrote udf_block_map to handle next extents and descs across
* block boundaries (which is not actually allowed)
* 12/20/98 added support for strategy 4096
