[Bug 2015355] [NEW] Please backport patches for false atari partition detection to Ubuntu 20.04

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Steve Langasek (vorlon):

There are three patches in util-linux upstream that were released in
util-linux 2.37 and prevent false detection of the atari partition table
with blkid and wipefs. We see this mostly on LUKS devices initialised
via luksFormat reporting there is an atari partition table on the device
when it is empty. This causes issues in various places, but one key
example for us is in kubernetes where mount-utils will refuse to format
the device (https://github.com/kubernetes/mount-
utils/blob/732a08ae47571516020ef99c303c70c1fa5b3e6c/mount_linux.go#L437-L441)

RedHat backported these fixes to RHEL 8 under
https://bugzilla.redhat.com/show_bug.cgi?id=2060030 and it would be
helpful if Ubuntu also backported them to Ubuntu 20.04 which is still
running util-linux 2.34

The request is to backport patches based on the https://github.com/util-
linux/util-linux/issues/1159 upstream report.
