Bug description:
== SRU Justification, Xenial, Artful ==
Running ZFS userspace utils with newer 0.7.x ZFS kernel drivers breaks
ZFS send/receive because of changes in the ioctl command structure.
== Testcase ==
ubuntu ADT ZFS tests autotests/client/tests/ubuntu-zfs-smoke-tests
will show a failure in ZFS SEND, with userspace zfs tools segfaulting.
== Fix ==
Fix is to detect if ZFS kernel driver is version 0.7.x and copy the
0.6.5.x zfs ioctl command structure to a ZFS 0.7.x version, call the
ioctl() and then copy the result back.
== Regression Potential ==
This will only affect the ZFS ioctl interface and this can be fully
tested using the ZFS autotests with 0.7.0 and 0.6.5.x ZFS enabled
kernels to check for the compatibility change regressions.
