Since this affects root on ZFS and the original patch no longer applies
(and ZFS on root) is not currently supported, I am reluctantly going to
close is issue. If a clean fix for ZFS on root for newer Zesty+
initramfs scripts is available I am happy to re-apply them for newer
releases. However, I am not going to forward port the original changes
since the delta is too large and I am not able to test these (as we
don't have ZFS on root by default).

Title:
  ZFS: Set elevator=noop on disks in the root pool

Status in zfs-linux package in Ubuntu:
  Won't Fix
Status in zfs-linux source package in Xenial:
  Fix Released
Status in zfs-linux source package in Zesty:
  Won't Fix

Bug description:
  ZFS-on-Linux has its own I/O scheduler, so it sets the "noop" elevator
  on whole disks used in a pool.
  https://github.com/zfsonlinux/zfs/issues/90

  It does not set the scheduler for a disk if a partition is used in a
  pool out of respect for the possibility that there are non-ZFS
  partitions on the same disk.
  https://github.com/zfsonlinux/zfs/issues/152

  For regular pools, the recommendation is to use whole disks. For a
  root pools, it's just the opposite. The typical case is that
  partitions are used. And, for root pools, it is unlikely that the same
  disks have non-ZFS filesystems.

  The debdiff in comment #5 applies cleanly to the latest package and
  functions correctly. This is an important change for root-on-ZFS
  users. It has no effect on non-root-on-ZFS installs, because the code
  is only in the zfs-initramfs package.
