commit: 30f359a6f9da65a66de8cadf959f0f4a0d498bba From: Nicholas Bellinger <[email protected]> Date: Wed, 10 Apr 2013 15:00:27 -0700 Subject: target: Fix incorrect fallthrough of ALUA Standby/Offline/Transition CDBs
This patch fixes a bug where a handful of informational / control CDBs that should be allowed during ALUA access state Standby/Offline/Transition where incorrectly returning CHECK_CONDITION + ASCQ_04H_ALUA_TG_PT_*. This includes INQUIRY + REPORT_LUNS, which would end up preventing LUN registration when LUN scanning occured during these ALUA access states.
