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. # 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 nr_writeback_temp 0 nr_isolated_anon 0 nr_isolated_file 0 nr_shmem 260 nr_dirtied 1050 nr_written 938 numa_hit 962872 numa_miss 0 numa_foreign 0 numa_interleave 8617 numa_local 962872 numa_other 0 nr_anon_transparent_hugepages 0 [akpm@linux-foundation.org: no externs in .c files] Signed-off-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Cc: Michael Rubin <mrubin@google.com> Cc: Wu Fengguang <fengguang.wu@intel.com> Acked-by: David Rientjes <rientjes@google.com> Cc: Randy Dunlap <rdunlap@xenotime.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
