nouveau_abi16_ioctl_channel_alloc() and nouveau_cli_init() simply call their corresponding *_fini() counterpart. This can lead to nouveau_sched_fini() being called without struct nouveau_sched ever being initialized in the first place. Instead of embedding struct nouveau_sched into struct nouveau_cli and struct nouveau_chan_abi16, allocate struct nouveau_sched separately, such that we can check for the corresponding pointer to be NULL i...

nouveau_sched_init() uses the function drm_sched_init(). The latter function has parameters called "hang_limit" and "timeout" in its API documentation. nouveau_sched_init(), however, defines a variable called "job_hang_limit" which is passed to drm_sched_init()'s "timeou...
