At LSF/MM'16 and Linux FAST (https://lwn.net/Articles/685499/) there were discussions about adding stream IDs to the block/device layer to allow higher layers (filesystems, applications) to identify IO streams so lower layers (SSDs, hybrid storage, etc.) can make better allocation/placement decisions. It would be useful to get an update on the state of this work, and discuss any obstacles that need to be resolved for getting this code landed. Cheers, Andreas
