Subject: Re: [PATCH V2 4/4] cpufreq: schedutil: irq-work and mutex are only used in slow path
Date: Thu, 24 Nov 2016 05:53:37 +0100 [thread overview]
Message-ID: <20161124045337.GB18417@gmail.com> (raw)
In-Reply-To: <a099804224d5e980a78668fa111e0564b0f44029.1479197311.git.viresh.kumar@linaro.org>
Firstly, please start changes to scheduler code with a verb. 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?

Is this an optimization? A correctness fix?
Thanks,
Ingo
