Date: Fri Apr 17 2015 - 09:33:56 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: John Soni Jose <sony.john-n@xxxxxxxxxx>

commit 2e7cee027b26cbe7e6685a7a14bd2850bfe55d33 upstream.

Kernel panic was happening as iscsi_host_remove() was called on
a host which was not yet added.
