Well, part of the idea behind ZFS is that these parts are _not_ separated in
"layers" -- for instance, the filesystem can push data down to the RAID level
to determine the stripe size used.

Whether this is a good idea is of course hotly debated, but I don't think you
can port just the filesystem part and call it a day.
