Thank you for reporting it. I am currently looking into it. It appears
that the device is being freed after it's closed, which could indicate
that we overlooked something at close, just a hypothesis at this point.

Hmm, I'm unable to reproduce the issue. However, it's possible that the
O_EXCL open for the 'btrfs check' command failed because 'systemd-udev'
was scanning the btrfs device at the same time. I noticed from the dmesg
that the 'systemd-udevd' thread was running [1] at some point. I'm not
entirely sure if it raced with the 'btrfs check' command to successfully
acquire the O_EXCL lock. If you could send me the 'testcase.full' and
'testcase.out.bad' logs from the system, I could verify the issue.

Could you please also attach the full log and out.bad file for
the test case in the report as shown below?

and
/lkp/benchmarks/xfstests/results/btrfs/<test-case-number>.out.bad
as attached. Thanks!
