How well does the simplified ida allocator work for tens of thousands of disks, at scan time? SCSI is notorious for setting up and tearing down a ton of queues at probe time. Unless we have more testing than 'it works on my laptop and saves 16k', I'm not super intereted in the patch. -- Jens Axboe -- To unsubscribe from this list: send the line "unsubscribe linux-block" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
