That's exactly what happens with the patch. Note that in the current upstream
version there are several slab checks scattered all over.

In this case for example, I'm removing it from __alloc_bootmem_node(), but the
first code line of__alloc_bootmem_node_nopanic() is:

        if (WARN_ON_ONCE(slab_is_available()))
                return kzalloc(size, GFP_NOWAIT);

You're only talking about mm/bootmem.c and not mm/nobootmem.c, and notice 
that __alloc_bootmem_node() does not call __alloc_bootmem_node_nopanic(), 
it calls ___alloc_bootmem_node_nopanic().

Holy cow, this is an underscore hell.


Thanks,
Sasha
