Page daemon output is now regulated by a PID controller with a setpoint of v_free_target. Moreover, the page daemon now wakes up regularly rather than waiting for a wakeup from another thread. This means that the free page count is unlikely to drop below the old zfs_arc_free_target value, and as a result the ARC was not readily freeing pages under memory pressure. Address the immediate problem by updating zfs_arc_free_target to match the page daemon's new behaviour.
