 /*
- *      idetape_mtioctop is called from idetape_chrdev_ioctl when

+ * Called from idetape_chrdev_ioctl when the general mtio MTIOCTOP ioctl is
+ * requested.
  *
- *      We currently support the following mtio.h operations:
+ * Note: MTBSF and MTBSFM are not supported when the tape doesn't support
+ * spacing over filemarks in the reverse direction. In this case, MTFSFM is also
+ * 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.
- *
- *      Note:
- *
- *              MTBSF and MTBSFM are not supported when the tape doesn't
- *              support spacing over filemarks in the reverse direction.
- *              In this case, MTFSFM is also usually not supported (it is
- *              supported in the rare case in which we crossed the filemark
- *              during our read-ahead pipelined operation mode).
- *              
- *      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.
- *
- *      The following commands are currently not supported:
- *
- *      MTFSS, MTBSS, MTWSM, MTSETDENSITY,
- *      MTSETDRVBUFFER, MT_ST_BOOLEANS, MT_ST_WRITE_THRESHOLD.
