Thanks, I'll have to add that to my clean ups. I originally had it as 
kmalloc, and just set the last entry to NULL by hand. Then I realized 
that if an error happened during initialization of one of the entries, it 
may not be NULL, so I went back and changed it to kzalloc, never thinking 
about kcalloc.
