+Explanation for various VM statistics
+-------------------------------------
+
+These statistics are available through /proc/vmstats
+/proc/meminfo and through /sys/devices/system/node/nodeX/meminfo
+on a NUMA system.
+
+The counters fall into two categories, the per zone counters and
+the per cpu counters. The per zone counters are used to count
+the number of pages for various purposes. The per cpu counters
+are used to count events of various kinds.
+
+The per zone counters are:
+
+Value			meminfo		vmstat		NUMA meminfo	zoneinfo
+--------------------------------------------------------------------------------
+Size of pagecache	Cached:		nr_pagecache	Pagecache:	pagecache
+Anonymous pages		Anonymous:	nr_anon		Anonymous:	anon
+Mapped pagecache	Mapped:		nr_mapped	Mapped:		mapped
+Slab pages		Slab:		nr_slab		Slab:		slab
+Pagetable pages		PageTables:	nr_pagetable_pages -		pagetable
+Dirty pagecache pages	Dirty:		nr_dirty	Dirty:		dirty
+Pages under writeback	Writeback:	nr_writeback	Writeback:	writeback
+NFS Unstable pages	-		nr_unstable	Unstable:	unstable
+Bounce buffers		-		nr_bounce	Bounce:		bounce

+
+In order to make this consisten we will
+
+1. Rename /proc/meminfo Cached to Pagecache:
+2. Add PageTables to NUMA meminfo
+3. Remove the USED from the Numa Meminfo
+
+Order in /proc/meminfo
