    Subject[RESEND PATCH v3 0/2] VT: Add ability to get font requirements
    Date
    We now have KD_FONT_OP_SET_TALL, but in fact such large fonts cannot be
    loaded. No console driver supports tall fonts. Unfortunately, userspace
    cannot distinguish the lack of support in the driver from errors in the
    font itself. In all cases, EINVAL will be returned.

    This patchset adds a separate ioctl to obtain the font parameters
    supported by the console driver.

    v3:
    * Added the use of the in_range macro.
    * Squashed the commits that add ioctl to console divers.

    v2:
    * Instead of the KDFONTOP extension, a new ioctl has been added to
    obtain font information.

    Alexey Gladkov (2):
    VT: Add KDFONTINFO ioctl
    VT: Allow to get max font width and height
