Subject: Re: [PATCH 3/6] cpufreq: Export user_policy min/max
Date: Fri, 6 Jan 2012 07:33:20 -0800	[thread overview]
Message-ID: <20120106153320.GF12530@mgross-G62> (raw)
In-Reply-To: <1325810186-28986-4-git-send-email-amiettinen@nvidia.com>

Why do you need to export these values here and from the pmqos ABI?

I don't think we want this change.  Also, isn't it redundant WRT
existing CPU freq govoner sysfs output?
