`/dev/disk/by-id/` names of newly created nvme namespaces are changing after I/O is run to the namespace.

Issue

• /dev/disk/by-id/nvme-Dell* names of newly created nvme namespaces are changing after I/O is run to the namespace. Issue is reproducible with following steps

  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.
