[Bug 1445195] Re: [Hyper-V] Kernel patches for storvsc

 

It sounds like the following commit is also needed to solve bug 1456985
:


commit dc45708ca9988656d706940df5fd102672c5de92
Author: K. Y. Srinivasan <kys@xxxxxxxxxxxxx>
Date:   Fri May 1 11:03:02 2015 -0700

    storvsc: Set the SRB flags correctly when no data transfer is needed


That commit was requested in bug 1454758 .  I'm going to mark bug 1454758 as a duplicate of this bug and build all of the commits requested in that bug and this bug together in a test kernel.
