You forgot a batch_complete_init(). With that, it works. Single device is ~1050K now, so still slower than jaio without batching (which was ~1220K). But it's an improvement over kaio-dio, which was roughly ~930K IOPS. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
