Well, it exsits in the block layer (the ability to specify an existing tag map to blk_queue_init_tags(). Jens is going to expose a bit more of the tag map machinary to make that useful, then for host global tags, we'll generate a single tag map and share it amongst all the queues. > Just a small comment, isn't the scsi_populate_tag_msg() function > quietly truncating the request->tag value? Not for SPI, no. However, we probably need a different API for the sixteen bit tag values FC can use? James
