So how does this play out if there is another user? Do they want a num= and
trust= if not, then the AUDIT_FANOTIFY record will have multiple formats
which is not good. I'd rather suggest something generic that can be
interpreted based on who's attached to fanotify. IOW we have a fan_type=0 and
then followed by info0= info1= the interpretation of those solely depend on
fan_type. If the fan_type does not need both, then any interpretation skips
what it doesn't need. If fan_type=1, then it follows what arg0= and arg1= is
for that format. But make this pivot on fan_type and not actual names.

Please, let's keep AUDIT_FANOTIFY normalized but pivot on fan_type.
