Neil, This is another attempt to make raid5 stripe handling multi-threading. Recent workqueue improvement for unbound workqueue looks very promising to the raid5 usage. I had details in the first patch. The patches are against your tree with patch 'raid5: make release_stripe lockless' and 'raid5: fix stripe release order' but without 'raid5: create multiple threads to handle stripes' Thanks, Shaohua -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
