类型参数名称
struct rb_root_cached *root
struct zap_details *details
2814  vba等于Offset (within vm_file) in PAGE_SIZEunits
2815  vea等于vba加vma_pages(vma)减1
2816  zba等于Lowest page->index to unmap
2817  如果zba小于vba则zba等于vba
2819  zea等于Highest page->index to unmap
2820  如果zea大于vea则zea等于vea
2823  unmap_mapping_range_vma(vma, ((zba - vba) << PAGE_SHIFT determines the page size ) + Our start address within vm_mm. , ((zea - vba + 1) << PAGE_SHIFT determines the page size ) + Our start address within vm_mm. , details)
