Title:
  [Hyper-V] storvsc messages for CD-ROM medium not present tray closed

Status in linux package in Ubuntu:
  Triaged

Bug description:
  The below can be seen with any distribution running on a Generation 2
  VM.

  There is a verified patch for this, however it has been scheduled only for the 4.8 scsi-queue.
  As it a small patch which has been verified by KY and also accepted in the patch queue, will you be able to include this as part of the 16.04 rebase to 4.6, and as well for 14.04 and 15.10?

  Patch can be found at https://patchwork.kernel.org/patch/9131929/

  Description of problem:
  When starting and shutting down a Gen2 VM, at least 20-30 messages are recorded for storvsc with the below sample:
  [storvsc] Sense Key : Not Ready [current]
  [storvsc] Add. Sense: Medium not present - tray closed

  Steps to Reproduce:
  1. create a Generation2 VM
  2. start VM and observe the system logs
  3. multiple messages for the cd-rom are recorded from storvsc

  Actual results:
  even without a CD-ROM unit attached, the messages would appear.
  Having an ISO attached or not would still produce the same messages.
