So far as I know, it stores some user's config and cpufreq_update_policy() bases on the data in the struct to start a new policy. Cpu thermal driver （/driver/thermal/cpu_cooling.c）also will its value to update freq policy when receive a cpufreq policy adjust notification.
Yeah, but how are these different from policy->min/max/policy/governor? Why do we need to replicate this information?
From my understanding.policy->min/max may be modified by some drivers but the user_policy only store user space config and should not be changed by other reason. :)
Yes, that was the original idea IIRC, so separate user settings from stuff that may be changed internally by the kernel.
