在对命名空间运行 I/O 后，新创建的 nvme 命名空间的 '/dev/disk/by-id/` 名称改变了。

Issue

• 在对命名空间运行 I/O 后，新创建的 nvme 命名空间的名称 /dev/disk/by-id/nvme-Dell* 改变了。可以通过以下步骤重现问题

  1. Connect 3 nvme drives with namespace support.
  2. Create 4 namespaces on each drive with same size.
  3. Attach to the controller.
  4. Please note /dev/disk/by-d nvme-Dell* names before I/O starts.
  5. RUN the I/O test on all the newly created namespaces .
  6.     dd if=/dev/random of=${DRIVE}n1 bs=1G count=50 &
         dd if=/dev/random of=${DRIVE}n2 bs=1G count=50 &
         dd if=/dev/random of=${DRIVE}n3 bs=1G count=50 &
         dd if=/dev/random of=${DRIVE}n4 bs=1G count=50 &                          
  7. Check the /dev/disk/by-id nvme-Dell* namespace names.
