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.
