This series adds support for sharing tags (and thus requests) between multiple request_queues. We'll need this for SCSI, and I think Martin also wants something similar for nvme. Besides the mess with request contructors/destructors the major RFC here is how the blk_mq_alloc_shared_tags API should look like. For now I've been lazy and reused struct blk_mq_reg, but that feels a bit cumbersome. Either a separate blk_mq_tags_reg or just passing the few arguments directly would work fine for me. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
