From: Michal Hocko <mhocko@xxxxxxxx>
Subject: vmstat: make vmstat_update deferrable
0eb77e988032 ("vmstat: make vmstat_updater deferrable again and shut down
on idle") made vmstat_shepherd deferrable. vmstat_update itself is still
useing standard timer which might interrupt idle task. This is possible
because "mm, vmstat: make quiet_vmstat lighter" removed
cancel_delayed_work from the quiet_vmstat. Change vmstat_work to use
DEFERRABLE_WORK to prevent from pointless wakeups from the idle context.
