When testing this case on my machine, it reports the following error: umount: /mnt/xfstests/scratch: target is busy. xfs_db: /dev/sda11 contains a mounted filesystem scratch_unmount failed, so _scratch_xfs_db reports scratch_dev is a mounted filesystem. It seems filesystem has something to be doing. To avoid this, just add a 100ms sleep before scratch_umount.
