Bug Description

btrfs-prog v4.16.x shipped with Ubuntu 18.10 cosmic has a regression that prevent incremental backup between subvolumes which have parent subvolume mounted on "/".

Ubuntu installer allows btrfs as install root and makes subvolume "@". `do-release-upgrade` makes snapshots "@apt-snapshot-*" while upgrading. In this case, incremental backup between those @apt-snapshot-* cannot be taken unless umount the root subvolume

The fix has been merged into upstream v4.17, can be found here
