struct mm_struct *mm
struct vm_area_struct *vma
2562  nr_accounted等于0
2565  update_hiwater_vm(mm)
2566  循环
2567  nrpages等于vma_pages(vma)
2569  如果Flags, see mm.h. 按位与Is a VM accounted object 则nr_accounted加等于nrpages
2571  vm_stat_account(mm, Flags, see mm.h. , - nrpages)
2572  vma等于Close a vm structure and free it, returning the next.
2573  当vma循环
