函数原型：static int walk_hugetlb_range(unsigned long addr, unsigned long end, struct mm_walk *walk)

返回类型：int

参数：

类型参数名称
unsigned longaddr
unsigned longend
struct mm_walk *walk
186  vma等于vma
187  h等于hstate_vma(vma)
189  hmask等于huge_page_mask(h)
190  sz等于huge_page_size(h)
192  ops等于ops
193  err等于0
195  循环
196  next等于hugetlb_entry_end(h, addr, end)
197  pte等于huge_pte_offset(mm, addr & hmask, sz)
199  如果pte则err等于hugetlb_entry(pte, hmask, addr, next, walk)
201  否则如果pte_hole则err等于pte_hole(addr, next, walk)
204  如果err则退出
206  当addr等于next, addr不等于end循环
208  返回:err
