So this doesn't pass for me but it's not because we're broken, it's
because the test is broken. What you should do is run sync after you
do the rm, and then capture the output of btrfs qgroup show, and then
do the rescan and redo qgroup show and make sure the numbers match. I
did this in my qgroup test, you can look there as an example. Thanks,
Let's take a look at my test flows:
step1: write some random data to fs tree and then create a snapshot of
fs tree.
step2: also try to write some random data to newly created snapshot.
step3: enable quota and wait quota rescan finished.(btrfs quota rescan -w)
step4: remove all files and sync btrfs filesystem.
So i did a simple test that if we don't create snapshot here, i get
qgroup accounting
right here, so i think it is realted to qgroup accounting that differs
'refer' and 'excl'.
Thanks,
Wang
