    storvsc: Set the SRB flags correctly when no data transfer is needed
    
    BugLink: http://bugs.launchpad.net/bugs/1439780
    
    Set the SRB flags correctly when there is no data transfer.  Without this
    change some IHV drivers will fail valid commands such as TEST_UNIT_READY.


This commit was included per bug 1439780 and is confirmed to have resolved that bug.   The 3.19.0-22 kernel is now in the proposed repository.  

Would it be possible for you to test this latest kernel and post back if it resolves this bug?
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. 

Thank you in advance!

Bug description:
  The following critical bugfix has been accepted into the upstream
  kernel. It is needed for 15.10, 15.02, 14.10, 14.04 and 14.04 HWE
  (and, by extension, 12.04 and 12.04 HWE). We have seen IHV drivers in
  the field throw errors and time out due to receiving SRB flags set
  when no data transfer is expected.
