| reuse_swap_page | We can write to an anon page without COW if there are no other references* to it. And as a side-effect, free up its swap: because the old content* on disk will never be read, and seeking back there to write new content |
| try_to_free_swap | If swap is getting full, or if there are no more mappings of this page,* then try_to_free_swap is called to free its swap space. |
