3.6.11.3 stable review patch. If anyone has any objections, please let me know.
------------------ From: Nicholas Bellinger <[email protected]> [ Upstream commit 30f359a6f9da65a66de8cadf959f0f4a0d498bba ] 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.
