Hi Paul,

I noticed that this patch has remained in the testing branch for some 
time, while the other patches in the same batch have already moved into 
the experimental/merged and for-next branch.

When testing locally by merging the current testing branch onto the 
latest for-next, I observed merge conflicts in the related areas. I 
would be glad to rebase the patch onto the current tree and send a new 
version if that would help resolve the conflicts.

Please let me know whether you would prefer me to prepare a rebased v3, 
or if the merge will be handled on your side.

Happy to rebase and resend if that would help.

Best regards,
Pincheng Wang
