Nothing is changing with respect to those write hints as a result of this series, if that's what you mean. The driver hadn't been checking the write hint before, and this patch set continues that pre-existing behavior. For this series, the driver utilizes a new field: "write_stream". Mapping the inode write hint to an FDP stream for other filesystems remains an open topic to follow on later.
