函数名称:llow_pfn - look up PFN at a user virtual address*@vma: memory mapping*@address: user virtual address*@pfn: location to store found PFN* Only IO mappings and raw PFN mappings are allowed.* Return: zero and the pfn at @pfn on success, -ve otherwise.
函数原型:int follow_pfn(struct vm_area_struct *vma, unsigned long address, unsigned long *pfn)
返回类型:int
参数:
类型 | 参数 | 名称 |
---|---|---|
struct vm_area_struct * | vma | |
unsigned long | address | |
unsigned long * | pfn |
4391 | 如果非Flags, see mm.h. 按位与Memory mapped I/O or similar 按位或Page-ranges managed without "struct page", just pure PFN 的值的值则返回:ret |
4394 | ret等于follow_pte(The address space we belong to. , address, & ptep, & ptl) |
4398 | pte_unmap_unlock(ptep, ptl) |
4399 | 返回:0 |
