[PATCH 4/9] target: Add TCM_MISCOMPARE_VERIFY sense handling
From: Nicholas A. Bellinger
Date: Tue Aug 20 2013 - 16:26:23 EST
From: Nicholas Bellinger <nab@xxxxxxxxxxxxx>
This patch adds TCM_MISCOMPARE_VERIFY (ASC=0x1d, ASCQ=0x00) sense
handling to transport_send_check_condition_and_sense(), which is
required for a COMPARE_AND_WRITE comparision failure.
