These resources include the kernel, which has potentially many non-preemptible critical sections guarded by one or more different synchronization primitives. While primitives such as FIFO locks bound the waiting time to enter a critical section, they do not distinguish the importance of individual tasks competing for shared resource access. To address this, we consider a priority-aware spinlock, which reduces the average delay of more important tasks while maintaining a worst-case bound on lock waiting time.
