Hi,
I didn't add umount at end of the test because...
_check_btrfs_filesystem() does it, which gets called as this test does
not specify _require_scratch_nocheck
----------------
_check_btrfs_filesystem()
{
device=$1
# If type is set, we're mounted
type=`_fs_type $device`
ok=1
if [ "$type" = "$FSTYP" ]
then
# mounted ...
mountpoint=`_umount_or_remount_ro $device` <----
fi
btrfsck $device >$tmp.fsck 2>&1
----------------
I faced the similar problem on some other tests and I found
adding the delay is the right approach. for eg:
--------------------------

The tests mount the second device in the device pool but never unmount
it, causing the next test to fail.
Example:
$ cat local.config
export TEST_DEV=/dev/sdb
export TEST_DIR=/home/fdmanana/btrfs-tests/dev
export SCRATCH_MNT="/home/fdmanana/btrfs-tests/scratch_1"
export SCRATCH_DEV_POOL="/dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg"
export FSTYP=btrfs
$ ./check btrfs/125 btrfs/126

Failed 1 of 2 tests
So just make sure those test unmount the device before they finish.
