mm/swap: use helper is_swap_pte() in swap_vma_readahead
Patch series "A few cleanup patches for swap".
This series contains a few patches to fix the comment, remove unneeded
return value, use some helpers and so on. More details can be found in
the respective changelogs.

Use helper is_swap_pte() to check whether pte is swap entry to make code
