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.
