返回类型：void

参数：

类型参数名称
struct seq_file *m
pg_data_t *pgdat
struct zone *zone
1564  seq_printf(m, "Node %d, zone %8s", 全局结点ID, 内存域的惯用名称(NORMAL DMA HIGHMEM))
1565  如果is_zone_first_populated(pgdat, zone)则
1566  seq_printf(m, "\n per-node stats")
1567  以i小于NR_VM_NODE_STAT_ITEMS循环
1568  seq_printf(m, "\n %-12s %lu", node_stat_name(i), Determine the per node value of a stat item.)
1572  seq_printf(m, "\n pages free %lu\n min %lu\n low %lu\n high %lu\n spanned %lu\n present %lu\n managed %lu", zone_page_state(zone, First 128 byte cacheline (assuming 64 bit words) ), min_wmark_pages(zone), low_wmark_pages(zone), high_wmark_pages(zone), 内存域中页的总数, 内存域中实际上可用的页数目, zone_managed_pages(zone))
1588  seq_printf(m, "\n protection: (%ld", 关键性内存分配[0])
1591  以i小于ARRAY_SIZE - get the number of elements in array @arr*@arr: array to be sized(关键性内存分配)循环seq_printf(m, ", %ld", 关键性内存分配[i])
1593  seq_putc(m, ')')
1596  如果非Returns true if a zone has memory 则
1597  seq_putc(m, '\n')
1598  返回
1601  以i小于NR_VM_ZONE_STAT_ITEMS循环seq_printf(m, "\n %-12s %lu", zone_stat_name(i), zone_page_state(zone, i))
1606  以i小于NR_VM_NUMA_STAT_ITEMS循环seq_printf(m, "\n %-12s %lu", numa_stat_name(i), zone_numa_state_snapshot(zone, i))
1611  seq_printf(m, "\n pagesets")
1612  遍历在线CPU(i)
1615  pageset等于per_cpu_ptr(CPU热/冷页帧列表, i)
1616  seq_printf(m, "\n cpu: %i\n count: %i\n high: %i\n batch: %i", i, count, high watermark, emptying needed , chunk size for buddy add/remove )
1630  seq_printf(m, "\n node_unreclaimable: %u\n start_pfn: %lu", Number of 'reclaimed == 0' runs >= Maximum number of reclaim retries without progress before the OOM* killer is consider the only way forward., 内存域第一个页帧的索引)
