+ * usually not supported (it is supported in the rare case in which we crossed
+ * the filemark during our read-ahead pipelined operation mode).
  *
- *	MTFSF	-	Space over mt_count filemarks in the positive direction.
- *			The tape is positioned after the last spaced filemark.
+ * The following commands are currently not supported:
  *
- *	MTFSFM	-	Same as MTFSF, but the tape is positioned before the
- *			last filemark.
- *
- *	MTBSF	-	Steps background over mt_count filemarks, tape is
- *			positioned before the last filemark.
- *
- *	MTBSFM	-	Like MTBSF, only tape is positioned after the last filemark.

- *	MTWEOF	-	Writes mt_count filemarks. Tape is positioned after
- *			the last written filemark.
- *
- *	MTREW	-	Rewinds tape.
- *
- *	MTLOAD	-	Loads the tape.
- *
- *	MTOFFL	-	Puts the tape drive "Offline": Rewinds the tape and
- *	MTUNLOAD	prevents further access until the media is replaced.
- *
- *	MTNOP	-	Flushes tape buffers.
- *
- *	MTRETEN	-	Retension media. This typically consists of one end
- *			to end pass on the media.
- *
- *	MTEOM	-	Moves to the end of recorded data.
- *
- *	MTERASE	-	Erases tape.
- *
- *	MTSETBLK - 	Sets the user block size to mt_count bytes. If
- *			mt_count is 0, we will attempt to autodetect
- *			the block size.
- *
- *	MTSEEK	-	Positions the tape in a specific block number, where
- *			each block is assumed to contain which user_block_size
- *			bytes.
- *
- *	MTSETPART - 	Switches to another tape partition.
- *
- *	MTLOCK - 	Locks the tape door.
