      "message": "[SCSI] target: Fix t_transport_aborted handling in LUN_RESET + active I/O shutdown\n\nThis patch addresses two outstanding bugs related to\nT_TASK(cmd)-\u003et_transport_aborted handling during TMR LUN_RESET and\nactive I/O shutdown.\n\nThis first involves adding two explict t_transport_aborted\u003d1\nassignments in core_tmr_lun_reset() in order to signal the task has\nbeen aborted, and updating transport_generic_wait_for_tasks() to skip\nsleeping when t_transport_aborted\u003d1 has been set.  This fixes an issue\nwhere transport_generic_wait_for_tasks() would end up sleeping\nindefinately when called from fabric module context while TMR\nLUN_RESET was happening with long outstanding backend struct se_task\nnot yet being completed.\n\nThe second adds a missing call to\ntransport_remove_task_from_execute_queue() when\ntask-\u003etask_execute_queue\u003d1 is set in order to fix an OOPs when\ntask-\u003et_execute_list has not been dropped.  It also fixes the same\ncase in transport_processing_shutdown() to prevent the issue from\nhappening during active I/O struct se_device shutdown.\n\nSigned-off-by: Nicholas A.
