Thank your for your time and reply.

If this patch set is merged into the linux-next tree, I will send the 
third patch which targets at linux-next tree and converts existing users 
at later timer of this release cycle. Because there are new users that 
may use the old APIs comes into linux-next tree during the remaining time
of this release cycle.
