Anyways, I'll sit down this week and figure out what's going on with
Doug's active I/O shutdown regression.

The crash occurs in the core_tpg_del_initiator_node_acl() function
and a call to that function has been added recently in
target_fabric_nacl_base_release(). I think it was added through the
following patch:

    target: refactor init/drop_nodeacl methods
    
    By always allocating and adding, respectively removing and freeing
    the se_node_acl structure in core code we can remove tons of repeated
    code in the init_nodeacl and drop_nodeacl routines.  Additionally
    this now respects the get_default_queue_depth method in this code
    path as well.
