I approved it for artful before I actually checked if it's in bionic.
Seeing that we're in Final Freeze now, I guess it's not likely for us to
get this accepted in bionic, but as soon as we open-up for SRUs - please
be sure to get it uploaded to bionic/devel as well.
I'll conditionally approve xenial as well, but please remember we
probably won't publish it into -updates before we also have it in
bionic.

Title:
zvol_id throws ioctl_get_msg failed:Inappropriate ioctl for device
Status in zfs-linux package in Ubuntu:
In Progress
Status in zfs-linux source package in Xenial:
Fix Committed
Status in zfs-linux source package in Artful:
Fix Committed
Bug description:
== SRU Justification [XENIAL][ARTFUL] ==
Symlinks in /dev/zvol are not because /lib/udev/zvol_id exits with
ioctl_get_msg failed:Inappropriate ioctl for device. The core reason
is that the BLKZNAME with non-HWE userspace zfsutils is 1 char
different is size than the HWE kernel drivers.
== Fix ==
Change the userland zvol_id tool to use the V0.6.x ZFS_MAXNAMELEN size
and if that fails with ENOTTY retry with the V0.07.0 ZFS_MAXNAMELEN
size as a fallback compatibility call.
== Regression Potential ==
Very small, this changes zvol_id and keeps the original functionality
as well as adding V7 ZFS functionality as a fallback. At worse,
zvol_id will not work, but that's the same as the current broken
state.
== Testing ==
run /lib/udev/vol_id on /dev/zvol on Xenial with a 4.15 Xenial HWE
kernel. Without the fix one gets an ENOTTY errno failure. With the
fix zvol_id returns the zvol id and symlinks in /dev/zvol work.
---
Symlinks in /dev/zvol are not created because /lib/udev/zvol_id
crashes with ioctl_get_msg failed:Inappropriate ioctl for device.

without error.
