No that code needs a serious cleanup, I think you even (re-)introduced a
NULL pointer deref (but I didn't look too closely).

Simply re-instating the code that was removed isn't sufficient. 

Just write your patch as if its a new feature (and never even look at
the old code), you'll very probably end up with a much saner patch.
