hi, Alan
Thanks for your nice comments.
In theory it can go over 256 devices, In fact, it will waste more memories. :)
We really need a policy manager that works well.
FT guys may offer it one day. it's a little long time maybe. :(

When I was a student, I heard you left from kernel.
Welcome back to kernel, I didn't know that you are back. So sorry.

thanks,

xinhui
