Sorry, I didn't see Al's patch posted to the audit list and it wasn't in the 
audit next branch so I was a bit confused.

Regardless, it looks fine to me.  While normally I'd pull this into the audit 
next branch, in this case it is best if Al pulls this into his tree so it goes 
in with the original audit_file() patch.

If you have to respin this patch I might suggest moving the prototype to after 
the other audit_inode*() prototypes, e.g. just before audit_core_dumps(), but 
that is a pretty nit-picky thing.
