A finished fence exported to userspace via drm_syncobj /\nsync_file therefore keeps pointing at &sched->base after nouveau_sched_destroy(),\nand a later get_timeline_name() -- reachable unprivileged through\nSYNC_IOC_FILE_INFO -- dereferences freed memory (KASAN slab-use-after-free\nread).\n\nPer the dma-fence lifetime contract the exporter must keep the data backing a\nsignalled fence alive for an RCU grace period.  Free the scheduler-containing\nobject with kfree_rcu() instead of kfree()."
