Johannes Weiner poined out that the logic in commit [1741c877: mm: kswapd: keep kswapd awake for high-order allocations until a percentage of the node is balanced] is backwards. Instead of allowing kswapd to go to sleep when balancing for high order allocations, it keeps it kswapd running uselessly.
