Now, we track caller if tracing or slab debugging is enabled. If they are disabled, we could save one argument passing overhead by calling __kmalloc(_node)(). But, I think that it would be marginal. Furthermore, default slab allocator, SLUB, doesn't use this technique so I think that it's okay to change this situation. After this change, we can turn on/off CONFIG_DEBUG_SLAB without full kernel build and remove some complicated '#if' defintion. It looks more benefitial to me.
