Meanwhile, in the job submission thread,\nthe file_priv lock (#2) is taken first, and then the submitted_jobs\nlock (#1) is obtained when a job is added to the submitted jobs list.\n\n       CPU0                            CPU1\n       ----                    \t       ----\n  (for example due to a fault)         (jobs submissions keep coming)\n\n  lock(&vdev->submitted_jobs_lock) #1\n  ivpu_jobs_abort_all()\n  job_destroy()\n                                      lock(&file_priv->lock)           #2\n                                      lock(&vdev->submitted_jobs_lock) #1\n  file_priv_release()\n  lock(&vdev->context_list_lock)\n  lock(&file_priv->lock)           #2\n\nThis order of locking causes a deadlock.
