When a CFS task that was boosted by a SCHED_DEADLINE task boosts another CFS task (nested priority inheritance), Kernel panic is observed. Fixing priority inheritance changes the way how sched_deadline attributes are being inherited from original donor task.
Additional supporting patches are added to fix throttling of boosted tasks.
