Subject: vmscan: zone_reclaim don't call disable_swap_token()
From: KOSAKI Motohiro <kosaki.motohiro@xxxxxxxxxxxxxx>
Swap token don't works when zone reclaim is enabled since it was born.
Because __zone_reclaim() always call disable_swap_token() unconditionally.
This kill swap token feature completely. As far as I know, nobody want to
that. Remove it.
