This lead me down quite a long path to try to figure out why the existing
Coccinelle script (scripts/coccinelle/api/kmalloc_objs.cocci) didn't
catch these. The answer is the cleanup.h macros and poor interaction
with Coccinelle. I think I've got a work-around built now, and I'll send
a new tree-wide change to Linus before -rc2 gets cut.

Thanks for noticing these got missed!
