    I have also confirmed that it is a code change and not tied to
on-disk format. A version 22 zpool, when imported on a system with the
10U10 kernel, no longer includes aclmode.

    I have been told by Oracle Support (not first line, but someone
from engineering in response to an escalation) that the code is done
to put aclmode back in, and that an IDR can probably be cut against
the 10U10 kernel. They are finding out when it will be integrated.

    We need a snapshot deletion fix that is in zpool 26, but we also
need aclmode (or at least functional ACLs), which was removed in the
10U10 kernel.
