Ok, I think I see it: I think the mm/slab.c conversion of kmalloc(0) is

The problem? It returns ZERO_SIZE_PTR from __find_general_cachep(), not
from __kmalloc(). So anythign that uses __find_general_cachep() will get
an invalid cachep pointer, which was not the point.

actually break. Andi? Roland?
Christoph, please go over this and see if there are other cases like that.
__do_kmalloc_node probably.
