Subject: target: Fix incorrect fallthrough of ALUA Standby/Offline/Transition
CDBs
From: Nicholas Bellinger <[email protected]>
commit 30f359a6f9da65a66de8cadf959f0f4a0d498bba upstream.
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.
