we have to make sure the *swap address* doesnt go away, after putting the swap address in the segment pte. after we unlock the segment, the process could be killed or fault which would cause the swap address to be freed *before* we write the page to disk when it pulls the page from the cache and putswap() swap pte. keeping a reference to the page is no good. we have to hold on the swap address. this also has the advantage that we can now test if the swap address is still referenced and can avoid writing to disk. |
