    SubjectRe: Linux 2.6.22 released
    Are the shortlogs useful - yes .. they catch what appear to be mistakes

    Specifically: What happened to the aacraid ioctl security fix ? Did someone decide it
    wasn't needed or did it get lost somewhere on the way ?

    While this looks scary the only obvious exploit cases are where the user can
    open a device level file on an AACraid. Very few people put scanners or CD
    devices on one so the actual impact is probably minimal.
