** 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.
