The main difference with Glauber's patches is here: We try to

We feel that it's important to track everything, because there
are a lot of different slab allocations that may use significant
amounts of memory, that we may not know of ahead of time.
This is also the main source of complexity in the patchset.

Well, what are the performance implications of your patches? Can we 
reasonably expect distributions to be able to enable this thing on 
generic kernels and leave the feature disabled by default? Can we 
accommodate your patches to support Glauber's use case?
