Hi, I don't understand why the local variable box needs to be declared static here:
static struct intel_uncore_box * uncore_pmu_to_box(struct intel_uncore_pmu *pmu, int cpu) { static struct intel_uncore_box *box; box = *per_cpu_ptr(pmu->box, cpu); if (box) return box; .... } -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
