函数名称：zone_spanned_pages_in_node

函数原型：static inline unsigned long __init zone_spanned_pages_in_node(int nid, unsigned long zone_type, unsigned long node_start_pfn, unsigned long node_end_pfn, unsigned long *zone_start_pfn, unsigned long *zone_end_pfn, unsigned long *zones_size)

返回类型：unsigned long

参数：

类型参数名称
intnid
unsigned longzone_type
unsigned longnode_start_pfn
unsigned longnode_end_pfn
unsigned long *zone_start_pfn
unsigned long *zone_end_pfn
unsigned long *zones_size
6495  zone_start_pfn等于node_start_pfn
6496  以zone小于zone_type循环zone_start_pfn加等于zones_size[zone]
6499  zone_end_pfn等于zone_start_pfn加zones_size[zone_type]
6501  返回:zones_size[zone_type]
