Please elaborate. The only function that sets 'sess_tearing_down' and 'cmd_wait_set' is target_sess_cmd_list_set_waiting(). The iSCSI target driver does not call target_sess_cmd_list_set_waiting() and hence does not set any of these structure members. So how could this patch affect the iSCSI target driver?
