One of the general principles of the sysctl(3) API is that a user can
query the needed size for a sysctl result by passing in a NULL old pointer and a valid oldsize. The kern.proc.args sysctl handler broke this assumption by not calling SYSCTL_OUT() if the old pointer was NULL. Approved by: re (kib) MFC after: 3 days
