From 3533f8603d28b77c62d75ec899449a99bc6b77a1 Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Sat, 12 Jul 2014 09:48:32 -0700 Subject: drivers: scsi: storvsc: Correctly handle TEST_UNIT_READY failure 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. Signed-off-by: K. Y.
