+ * 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.
- *
- * MTUNLOCK - Unlocks the tape door.
