Just to add a bit of clarity, my original question was if there was any value 
in exposing the unset/invalid device and inode values, e.g. -1.  While I agree 
that there is value in auditing by dev/inode, I can't think of a reasonable 
situation where the user would need to pass an unset/invalid device and/or 
inode value into the kernel as part of an audit configuration command.
