How to prevent the policy to be freed between
cpufreq_cpu_get() and cpufreq_cpu_put() ?
kobject_get() increases the reference count of a policy and the policy
will only be freed when this is zero. And it will only be zero once all
cpufreq_cpu_get() are matched with corresponding cpufreq_cpu_put().
Is that an idea it supposed to be or fact ?
if (!cpufreq_suspended)
cpufreq_policy_free(policy);
static void cpufreq_policy_free(struct cpufreq_policy *policy)
{
free_cpumask_var(policy->related_cpus);
free_cpumask_var(policy->cpus);
kfree(policy);
}
It seems you just think about it ideally in mind.
Thanks,
