ZFS background/async destroy feature: MFC timeframe?

[Freddie Cash]

Good morning,

Just wondering when the zfs background/async destroy feature is
planned to be MFC'd?  Is the 9.1 release process holding it up?

Is there any way to manually patch it into 9-STABLE?

We have a system that is trying to destroy a temp filesystem on import
of the pool, which is taking way too long to do (over 3 days so far).
Was hoping to test out the background destroy to see if it would work
in this situation.
