Type:bool
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct page_vma_mapped_walk * | pvmw |
| 18 | pte = pte_offset_map(pmd, address) |
| 19 | If Not (flags & Avoid racy checks ) Then |
| 20 | If flags & Look for migarion entries rather than present PTEs Then |
| 21 | If Not heck whether a pte points to a swap entry Then Return false |
| 23 | Else |
| 39 | If heck whether a pte points to a swap entry Then |
| 43 | entry = Convert the arch-dependent pte representation of a swp_entry_t into an* arch-independent swp_entry_t. |
| 44 | If Not is_device_private_entry(entry) Then Return false |
| 46 | Else if Not pte_present( * pte) Then Return false |
| 52 | Return true |
