Hi Gopi Sai Teja,

Now I read previous thread at v1 carefully, I found Sergey already
sent a patch long time ago which is almost same one I suggested.
And he told he will send a patch soon so I want to wait his patch.
We are approaching rc6 now so it's not urgent.

Sergey, sorry for missing your patch at that time.
Could you resend your patch when you have a time? Please think
over better name of the function "zs_get_huge_class_size_watermark"

Thanks.
