Note: I skipped back to this because v12 only had the log vs v11.

That's not true as far as I can tell given that this is basically the
architecture from my previous posting.  The block code still maps the
rw hints into write streams, and file systems can do exactly the same.
You just need to talk to the fs maintainers and convince them it's a
good thing for their particular file system.  Especially for simple
file systems that task should not be too hard, even if they might want
to set a stream or two aside for fs usage.  Similarly a file system
can implement the stream based API.
