I can reproduce this in my local VM. I've traced ocfs2_dismount_volume and found that it hasn't been called. So EBUSY is returned in VFS layer. I guess something wrong when doing a copy with linked SQEs (normal copy seems no problem). Thanks, Joseph On 2/24/23 8:32 AM, Heming Zhao wrote: > Hello List, > > I found a weird bug on ocfs2.

I also test liburing examples apps on ext4 partition, everything looks fine.

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 ```

Hi all, These 2 patches added virtio-nvme to kernel and qemu, basically modified from virtio-blk and nvme code. As title said, request for your comments. Play it in Qemu with: -drive file=disk.img,format=raw,if=none,id=D22 \ -device virtio-nvme-pci,drive=D22,serial=1234,num_queues=4 The goal is to have a full NVMe stack from VM guest(virtio-nvme) to host(vhost_nvme) to LIO NVMe-over-fabrics
