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(). -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
