CC Doug  

Thanks for highlighting this for me, but I happened to catch it from the 
linux-mm list and was just looking into it.

It looks to me like a false positive since I am initializing the 
loc_rule variable in all paths outside of the list_for_each_entry() loop 
prior to its use on line 1497.

Ack, indeed the code looks right. Thanks for investigating.

If desired I can submit a new patch to make coccinelle happy.

I wonder if Cocci can detect writes. Let me add Julia for visibility.

If not we can use a different variable for the "check if already
exists" iteration? It could make the code easier to follow, IMHO.
Or leave it be.
