Subject: mm: per-node vmstat: show proper vmstats
From: KOSAKI Motohiro <kosaki.motohiro@xxxxxxxxxxxxxx>
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.
# cat /sys/devices/system/node/node0/vmstat
nr_free_pages 899224
nr_inactive_anon 201
nr_active_anon 17380
nr_inactive_file 31572
nr_active_file 28277
nr_unevictable 0
nr_mlock 0
nr_anon_pages 17321
nr_mapped 8640
nr_file_pages 60107
nr_dirty 33
nr_writeback 0
nr_slab_reclaimable 6850
nr_slab_unreclaimable 7604
nr_page_table_pages 3105
nr_kernel_stack 175
nr_unstable 0
nr_bounce 0
nr_vmscan_write 0
