    Patch in this message
    Subject[PATCH] remove error message on illegal ioctl
    This error message is uber annoying and needs to go.  Non-root can flood
    the console with this junk on invalid SCSI CD-ROM ioctl(),
    and that is exactly what gnome-cd does.

    An illegal ioctl() returns an error to the program. That is
    sufficient - we do not need KERN_ERROR warnings all over the place.
    Especially when any user can cause them at any rate.

    This patch, against 2.5.51, removes the message. Linus, please
