[PATCH] zoned vm counters: conversion of nr_slab to per zone counter

Browse Source 
- Allows reclaim to access counter without looping over processor counts.

- Allows accurate statistics on how many pages are used in a zone by
  the slab. This may become useful to balance slab allocations over
  various zones.
