Sorry, my bias is showing.  I always thought HPB was a useless
marketing feature and was against including it, so removing it is just
the world going back to being more correct.  To be honest, I also
didn't think you cared at all about UFS ...

Well, we put HPB in in spite of most of us thinking it was a bad idea
because there was a tiny chance it might work and it could be yanked
out if it didn't.  There's no reason not to extend the same courtesy to
zoned storage.

That's why RFC1925 exists, yes ...
