参数：

类型参数名称
pud_t *pud
unsigned longaddr

struct mm_walk *walk
35  ops等于ops
36  err等于0
38  pmd等于pmd_offset(pud, addr)
39  循环
40  again :
41  next等于pmd_addr_end(addr, end)
42  如果pmd_none( * pmd)或非vma则
43  如果pte_hole则err等于pte_hole(addr, next, walk)
45  如果err则退出
47  继续下一循环
53  如果pmd_entry则err等于pmd_entry(pmd, addr, next, walk)
55  如果err则退出
62  如果非pte_entry则继续下一循环
65  split_huge_pmd(vma, pmd, addr)
66  如果This is a noop if Transparent Hugepage Support is not built into* the kernel则转到:again
68  err等于walk_pte_range(pmd, addr, next, walk)
69  如果err则退出
71  当pmd自加, addr等于next, addr不等于end循环
73  返回:err
