[PATCH] Zone reclaim: resurrect may_swap
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 Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
