I have a v2 https://patchwork.kernel.org/cover/11208131/ patch based on Lenoard's v3 https://patchwork.kernel.org/patch/11193189/ to avoid conflicts when you apply Lenoard's v3 patch. It is fine you take my v1, but you will have conflicts if you take Leonard's v3 after apply my v1. Regards, Peng.

Okay, I replaced it with your v2 series. Thanks! Shawn
