+Subject: drivers: scsi: storvsc: Correctly handle TEST_UNIT_READY failure
+
+From: "K. Y. Srinivasan" <kys@microsoft.com>
+
+commit 3533f8603d28b77c62d75ec899449a99bc6b77a1 upstream.
+
+On some Windows hosts on FC SANs, TEST_UNIT_READY can return SRB_STATUS_ERROR.
+Correctly handle this. Note that there is sufficient sense information to
+support scsi error handling even in this case.
