Likely stupidity on my part.  It looks like a typo, that first if conditional 
should check "n->ino" instead of "inode->i_ino"; in __audit_getname() we 
record names without any inode numbers, so we need to see if this is one of 
those records.  Interesting that it passed my testing; either my testing is 
crap (always a strong possibility) or something else came to the rescue.  I'm 
still coming up to speed on the audit/VFS code ...

I'll fix that up and include in the next patchset once we resolve this issue.
