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.
