[sheepdog-users] Serialize inflight requests

[Vedvyas shanbhogue]

Thanks much . I will be glad to test the patch .

I included the serialization fix in my code but I still see this error
flagged sometimes. Are there any other fixes queued up that may address
this ?

In my test I copy a 4G .iso file to the vdi over iscsi and then compute a
sha hash on it. Sometimes I see this error show up and when it does the sha
hash also does not match .
