Just like static inline struct cpumask *cpu_l2c_shared_mask(int cpu) { return per_cpu(cpu_l2c_shared_map, cpu); } should check != must check. But it's perfectly fine if you're going to attempt to prove some bogus argument of yours - I can safely ignore you. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
