Zone reclaim has a huge impact on NUMA performance (f.e. our maximum
throughput with XFS is raised from 4GB to 6GB/sec / page cache contamination
of numa nodes destroys locality if one just does a large copy operation which
results in performance dropping for good until reboot).
This patch:
Resurrect may_swap in struct scan_control
