    axboe@nelson:[.]r/src/linux-2.6-block.git $ size block/scsi_ioctl.o
    text data bss dec hex filename
    2844 256 0 3100 c1c block/scsi_ioctl.o

    And it's not everything that's duplicated, basically only the ioctl
    parsing is. So either admit that there isn't a a lot of duplicated code,
    or "take some time" and point me at it. Otherwise refrain from making
    obviously false statements in the future.
