This patch addresses two outstanding bugs related to T_TASK(cmd)->t_transport_aborted handling during TMR LUN_RESET and active I/O shutdown. This first involves adding two explict t_transport_aborted=1 assignments in core_tmr_lun_reset() in order to signal the task has been aborted, and updating transport_generic_wait_for_tasks() to skip sleeping when t_transport_aborted=1 has been set. This fixes an issue where transport_generic_wait_for_tasks() would end up sleeping indefinately when called from fabric module context while TMR LUN_RESET was happening with long outstanding backend struct se_task not yet being completed. The second adds a missing call to transport_remove_task_from_execute_queue() when task->task_execute_queue=1 is set in order to fix an OOPs when task->t_execute_list has not been dropped. It also fixes the same case in transport_processing_shutdown() to prevent the issue from happening during active I/O struct se_device shutdown. Signed-off-by: Nicholas A.
