    Date
    From: Borislav Petkov <bbpetkov@yahoo.de>

    Those are already in mtio.h.

    + * 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.
    - *

    - * MTBSF and MTBSFM are not supported when the tape doesn't
    - * support spacing over filemarks in the reverse direction.

    - *
    - * 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,
