** Description changed:
A number of significant fixes have landed upstream for Hyper-V/Azure
clouds. The upstream devs for this recommend we apply the below list of
patches:

- sd: fix a bug in deriving the FLUSH_TIMEOUT from the basic I/O timeout
-
- Commit ID: 7e660100d85af860e7ad763202fff717adcdaacd added code to derive
the
- FLUSH_TIMEOUT from the basic I/O timeout. However, this patch did not use
the
- basic I/O timeout of the device. Fix this bug.

- Drivers: scsi: storvsc: Change the limits to reflect the values on the
host
-
- Hyper-V hosts can support multiple targets and multiple channels and
larger number of
- LUNs per target. Update the code to reflect this. With this patch we can
correctly
- enumerate all the paths in a multi-path storage environment.

currently
- implemented will be implemented on future Windows hosts. Even if they are
not

-
- Based on the negotiated VMBUS protocol version, we adjust the size of the
storage
- protocol messages. The two sizes we currently handle are pre-win8 and
post-win8.
- In WS2012 R2, we are negotiating higher VMBUS protocol version than the
win8
