This title: Subject: Re: [PATCH V2 4/4] cpufreq: schedutil: irq-work and mutex are only used in slow path is totally inadequate as it's a statement that says nothing about the _change_. What does the patch do? Does it add, remove, modify, fix or clean up? * Viresh Kumar wrote: > Execute the irq-work specific initialization/exit code only when the > fast path isn't available. Is this an optimization? A correctness fix? Thanks, Ingo
