Comment 0 for bug 2015355

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.
