After the lock is dropped, it is possible that the cpufreq_dev gets

Hi Guys,
The cpu_cooling driver is designed to use CPU frequency scaling to avoid
high thermal states for a platform. But it wasn't glued really well with
cpufreq core. For example clipped-cpus is copied from the policy
structure and its much better to use the policy->cpus (or related_cpus)

Yes, I'm leaning
CONFIG_STRICT_KERNEL_RWX is no longer selectable on most architectures.
Update this info to the documentation.

The prototypes of try_module_get are different with different macro.
When enable module and module unload, it returns bool, but others not.
Now unify their return value type as bool.

This patch adds an ioctl to flush data in faster device to cold area. User can
give device number and number of segments to move. It doesn't move it if there
is only one device.
The parameter looks like:
struct f2fs_flush_device {
u32 dev_num;/* device number to flush */
This patch gives slower device region to warm/cold data area more eagerly.
