Shriram Raja, and Richard West, "Bounded Priority-Aware Locking for Real-Time Kernels", arxiv, 2026 [] [] [arxiv]
We propose a Batched Priority Lock that first groups waiting tasks based on the order of their lock requests, and then determines the next lock holder according to priority within the waiting group, thus reducing the average waiting time for higher priority tasks compared to FIFO and priority-ordered locks.
