Current GT statistics use atomic64_t counters. Atomic operations incur a global coherency penalty. Transition to dynamic per-cpu counters using alloc_percpu(). This allows stats to be incremented via this_cpu_add(), which compiles to a single non-locking instruction. This approach keeps the hot-path updates local to the CPU, avoiding expensive cross-core cache invalidation traffic. Use for_each_possible_cpu() during aggregation and clear operations to ensure data consistency across CPU hotplug events.
