3.11.10.14 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Nicholas Bellinger <n...@linux-iscsi.org>
commit 83ff42fcce070801a3aa1cd6a3269d7426271a8d upstream.
This patch fixes a left-over se_lun->lun_sep pointer OOPs when one
of the /sys/kernel/config/target/$FABRIC/$WWPN/$TPGT/lun/$LUN/alua*
attributes is accessed after the $DEVICE symlink has been removed.
To address this bug, go ahead and clear se_lun->lun_sep memory in
core_dev_unexport(), so that the existing checks for show/store
ALUA attributes in target_core_fabric_configfs.c work as expected.
