[Bug 1451476] Re: grub-core/fs/zfs/zfs.c:1126: feature missing in check_pool_label:com.delphix:hole_birth

[Lars]

[Impact]
Grub is not able to boot the zpool and grub-probe is not able to detect the rootfs as zfs.

[Test Case]
If you enable the feature like this:
# zpool set feature at hole_birth=enabled <rootpool>

[Regression Potential]
I think the regression potential is low, because the new feature is added and will not be removed from upstream.

[Other Info]
Yes, Mathieu, I think it is just the patch you wrote:
 http://git.savannah.gnu.org/cgit/grub.git/commit/?id=a1007c6af296172c788f3346ff3ad30b9020f723

Thank you for your fast response!
   Lars

  Triaged

Bug description:
  Need support for zpool feature feature at hole_birth.

  The grub-probe in utopic/vivid is not able to boot a zpool which hast
  the feature at hole_birth enabled.

  I had to build grub from git://git.savannah.gnu.org/grub.git to get my Ubuntu up and running again.
  Could you please add the missing patches to grub to make it aware of feature at hole_birth?

  Kind regards,
     Lars
