Will this simple change implement the fast-up algorithm correctly?
- if (idle_ticks < (DBS_RATE / 5))
- cpufreq_driver_target(cpu_dbs_info[cpu].cur_policy,
- cpu_dbs_info[cpu].cur_policy->cur + 1,
- CPUFREQ_RELATION_L);
+ if (idle_ticks < (DBS_RATE / 5))
+ cpufreq_driver_target(cpu_dbs_info[cpu].cur_policy,
+ cpu_dbs_info[cpu].cur_policy->max,
+ CPUFREQ_RELATION_L);

"the" fast-up algorithm? Well, it surely _is_ a fast-up algorithm what you
propose:

However, please set CPUFREQ_RELATION_H here -- you don't want to go higher
than cur_policy->max.
