Zone reclaim locked breaks zone_reclaim_mode=1. If more than one thread allocates memory at the same time, it forces a premature allocation into remote NUMA nodes even when there's plenty of clean cache to reclaim in the local nodes.
Since we can get into concurrent reclaim from the direct reclaim path anyway, and seem to handle that correctly, removing this special case from zone reclaim looks fine.
