If you do not want to use stable, you could try to import the diff to 
your release src yourself.
The only change then is the mfi driver, the rest is just release.

But stable is not that bad to run, i know many people that run a stable 
release, just for this kind of things.
Many people runs 8.2 Stable for the latest ZFS version.
