An AVX-512 accelerated version of xor_gen for Linux software RAID parity generation and validation has been updated and shows performance improvements
RAID 5 and RAID 6 arrays in Linux rely on xor_gen for parity calculations, a computationally intensive task. AVX-512 optimizations can reduce CPU overhead for these operations, potentially improving throughput and latency for storage systems. This change primarily benefits high-performance or large-scale storage deployments where parity generation is a bottleneck
