    SubjectRe: [PATCH] kill HDIO_GETGEO_BIG_RAW ioctl

    28bit it is a free for all, and anything goes in linux because nobody is
    willing to commit and force anything over 8.4GB to LBA only. People think
    that "orphan sectors" are a bad thing. IFF one can only IO in LBA with
    the exception of sectors at or below the 8.4GB limit then one never needs
    to worry about rogue programs existing out in nowhere land.

    Cheers,
