I think you should add more description about the issue you're going to
test. I see only failures like
[root@dhcp-66-86-11 xfstests]# diff -u tests/btrfs/084.out /root/xfstests/results//btrfs/084.out.bad

but from the test I don't know why "8192 0" is expected result not "0 0"
Sure, I will add more description in V2 to explain why we are expecting
"0 0" here.

Better to use a tab not 4 spaces, maybe "new" should be updated too (in
another patch)
Thanx, will send another patch for "./new".

_scratch_mkfs first before you mount it.
And you need to remove $seqres.full before test, since you called
_run_btrfs_util_prog and it will dump commands and outputs to
$seqres.full, the file will keep growing over runs if you don't remove
it first.
rm -f $seqres.full
Great! thanx for your review.

I'm not sure if we need 100 iterations and sleeping 1 sec after each
iteration, that means we need 100s for a PASS run.
The 100sec is the limit for the loop, it means if the clean work is done
in 100sec, we will
break immediately. We don't have to wait for 100s in each test.

Please follow this code style, as Dave pointed before

if ; then

Yea, as this is my first test case for fstest, there are lots of silly
problems in it.
Thanx a lot for your review and help, will update it soon.
Thanx
