[PATCH] /proc/zoneinfo: fix vm stats display
This early break prevents us from displaying info for the vm stats thresholds if the zone doesn't have any pages in its per-cpu pagesets. So my 800MB i386 box says: Node 0, zone DMA pages free 2365 min 16 low 20 high 24 active 0 inactive 0 scanned 0 (a: 0 i: 0) spanned 4096 present 4044 nr_anon_pages 0 nr_mapped 1 nr_file_pages 0 nr_slab_reclaimable 0 nr_slab_unreclaimable 0 nr_page_table_pages 0 nr_dirty 0 nr_writeback 0 nr_unstable 0 nr_bounce 0 nr_vmscan_write 0 protection: (0, 868, 868) pagesets all_unreclaimable: 0 prev_priority: 12 start_pfn: 0 Node 0, zone Normal pages free 199713 min 934 low 1167 high 1401 active 10215 inactive 4507 scanned 0 (a: 0 i: 0) spanned 225280 present 222420 nr_anon_pages 2685 nr_mapped 1110 nr_file_pages 12055 nr_slab_reclaimable 2216 nr_slab_unreclaimable 1527 nr_page_table_pages 213 nr_dirty 0 nr_writeback 0 nr_unstable 0 nr_bounce 0 nr_vmscan_write 0 protection: (0, 0, 0) pagesets cpu: 0 pcp: 0 count: 152 high: 186 batch: 31 cpu: 0 pcp: 1 count: 13 high: 62 batch: 15 vm stats threshold: 16 cpu: 1 pcp: 0 count: 34 high: 186 batch: 31 cpu: 1 pcp: 1 count: 10 high: 62 batch: 15 vm stats threshold: 16 all_unreclaimable: 0 prev_priority: 12 start_pfn: 4096 Just nuke all that search-for-the-first-non-empty-pageset code. Dunno why it was there in the first place..
