Bug description:
Test failed with disk quota exceeded when trying to create subvolume,
and error traces could be found in the kernel log.
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.
Create subvolume '/tmp/mnt-6113077cd319e747875ec71227d2b5cb54e08c76/subv'
fallocate: fallocate failed: Disk quota exceeded
