I remember one important thing: you need to be careful with triple fault...when IIRC we just deal with maximum double fault. And I think, this has security implication.... even if you don't have root privilege, if somehow you can "break" into binary inside trusted path, it's like gaining control via /dev/{k,}mem Plus side: reduced kernel-user mode context switch... good for I/O intensive apps such as database IMHO. regards, Mulyadi. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
