Name:mfill_zeropage_pte
Proto:static int mfill_zeropage_pte(struct mm_struct *dst_mm, pmd_t *dst_pmd, struct vm_area_struct *dst_vma, unsigned long dst_addr)
Type:int
Parameter:
Type | Parameter | Name |
---|---|---|
struct mm_struct * | dst_mm | |
pmd_t * | dst_pmd | |
struct vm_area_struct * | dst_vma | |
unsigned long | dst_addr |
156 | If File we map to (can be NULL). Then |
159 | offset = linear_page_index(dst_vma, dst_addr) |
162 | If Value for the false possibility is greater at compile time(offset >= max_off) Then Go to out_unlock |
166 | If Not pte_none( * dst_pte) Then Go to out_unlock |
168 | set_pte_at(dst_mm, dst_addr, dst_pte, _dst_pte) |
171 | ret = 0 |
172 | out_unlock : |
173 | pte_unmap_unlock(dst_pte, ptl) |
174 | Return ret |
