Name:Locate a page of swap in physical memory, reserving swap cache space* and reading the disk if it is not already cached.* A failure return means that either the page allocation failed or that* the swap entry is no longer in use.
Proto:struct page *read_swap_cache_async(swp_entry_t entry, gfp_t gfp_mask, struct vm_area_struct *vma, unsigned long addr, bool do_poll)
Type:struct page
Parameter:
| Type | Parameter | Name |
|---|---|---|
| swp_entry_t | entry | |
| gfp_t | gfp_mask | |
| struct vm_area_struct * | vma | |
| unsigned long | addr | |
| bool | do_poll |
| 452 | retpage = __read_swap_cache_async(entry, gfp_mask, vma, addr, & page_was_allocated) |
| 455 | If page_was_allocated Then swap_readpage(retpage, do_poll) |
| 458 | Return retpage |
