RELENG_7 uses ZFS v13, RELENG_8 uses ZFS v18.

RELENG_7 and RELENG_8 both, more or less, behave the same way with
regards to ZFS.  Both panic on kmem exhaustion.  No one has answered my
question as far as what's needed to stabilise ZFS on either 7.x or 8.x.

The people who need to answer the question are those who are familiar
with the code.  Specifically: Kip Macy, Pawel Jakub Dawidek, and anyone
else who knows the internals.  Everyone else in the user community is
simply guessing + going crazy trying to figure out a solution.

As much as I appreciate all the work that has been done to bring ZFS to
FreeBSD -- and I do mean that! -- we need answers at this point.
