Subject[PATCH 3.16 233/357] Target/iser: Dont put isert_conn inside disconnected handler
Date
3.16-stable review patch.  If anyone has any objections, please let me know.

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

From: Sagi Grimberg <sagig@mellanox.com>

commit 0fc4ea701fcf5bc51ace4e288af5be741465f776 upstream.

disconnected_handler is invoked on several CM events (such
as DISCONNECTED, DEVICE_REMOVAL, TIMEWAIT_EXIT...). Since
multiple events can occur while before isert_free_conn is
invoked, we might put all isert_conn references and free
the connection too early.
