This patch exists in the Bionic kernel tree: https://kernel.ubuntu.com/git/ubuntu/ubuntu-bionic.git/commit/?id=6113077cd319e747875ec71227d2b5cb54e08c76 Invoking test 6113077cd319e747875ec71227d2b5cb54e08c76 fix 6113077cd319e747875ec71227d2b5cb54e08c76 Btrfs: fix missing qgroup reservation before fallocating Steps to reproduce: mkfs.btrfs <disk> mount <disk> <mnt> btrfs quota enable <mnt> btrfs sub create <mnt>/subv btrfs qgroup limit 10M <mnt>/subv fallocate --length 20M <mnt>/subv/data For the above example, fallocating will return successfully which is not expected, we try to fix it by doing qgroup reservation before fallocating.
