I'll take a look at a web archive of it, I don't follow -mm.

Slab pages isn't a useful tracking tool for two reasons. The first is
that some resources are genuinely a shared kernel managed pool and
should be treated that way - thats obviously easy to sort out.

The second is that slab pages are not the granularity of allocations so
it becomes possible (and deliberately influencable) to make someone else
allocate the pages all the time so you don't pay the cost. Hence the
beancounters track the real objects.

If it can do it in a human understandable way, configured at runtime
with dynamic sharing, overcommit and reconfiguration of sizes then
great. Lets see what Paul has to say.
