mm: per-node vmstat: show proper vmstats
commit 2ac390370a ("writeback: add
/sys/devices/system/node/<node>/vmstat") added vmstat entry. But
strangely it only show nr_written and nr_dirtied.
# cat /sys/devices/system/node/node20/vmstat
nr_written 0
nr_dirtied 0
Of course, It's not adequate. With this patch, the vmstat show all vm
stastics as /proc/vmstat.
