yes, the old kernel should be affected by this and we should have it in 
stable tree.

But I just have one concern: should I add stable to cc list the first 
time I create the patch? I am afraid not since it may be changed may 
times and have many revisions.

So my suggestion is that we go on the normal process, and when my patch 
get acked, I will resend it, add your ack and cc to stable. Agree? The 
same goes to other's patches.
