Hi Yingbo,

This is a change that breaks backward compatibility and not acceptable.

There is no such file in the mainline kernel.  So it looks like the patch set is based on some internal git repo instead of the upstream Linux kernel.  This kind of patches shouldn't be sent to the upstream mailing list for review.
