3.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Nicholas Bellinger <nab@linux-iscsi.org>
commit 683497566d48f86e04d026de1ee658dd74fc1077 upstream.
This patch adds a explicit memset to the login response PDU exception path in iscsit_tx_login_rsp().
This addresses a regression bug introduced in commit baa4d64b where the initiator would end up not receiving the login response and associated status class + detail, before closing the login connection.
