The CPU cooling driver uses the cpufreq policy, to get clip_cpus, the frequency table, etc. Most of the callers of CPU cooling driver's registration routines have the cpufreq policy with them, but they only pass the policy->related_cpus cpumask. The __cpufreq_cooling_register() routine then gets the policy by itself and uses it. It would be much better if the callers can pass the policy instead directly. This also fixes a basic design flaw, where the policy can be freed while the CPU cooling driver is still active.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
