Subject: [Ocfs2-devel] report BUG: io_uring triggers umount error
Date: Fri, 24 Feb 2023 08:32:51 +0800 [thread overview]
Message-ID: <20230224003251.otqzmap2f64o3fpf@c73> (raw)
Hello List,
I found a weird bug on ocfs2. I am busying with other jobs, if anyone have time
he/she could fix it. This bug is blocking fstest generic/013 test case, and also
blocking fstest to do later test cases.
How to trigger:
```
git clone git://git.kernel.dk/liburing.git
cd liburing
make
cd examples
mount -t ocfs2 /dev/sda /mnt
cp /etc/hosts /mnt/a
./link-cp /mnt/a /mnt/b
umount /mnt
```
umount trigger error message:
```
# umount /mnt
umount: /mnt: target is busy.
```
The umount error can only be triggered by liburing write operation.
Thanks,
Heming
