That is a dangerous thing to do. SLAB per cpu queues will contain foreign
objects which may cause troubles when pushing the objects back. I think we
may be lucky that these objects are consumed at boot. If all of the
foreign objects are consumed at boot then we are fine. At least an
explanation as to this issue should be added to the patch.
