Hi David
This series patches were ACKed by Pravin. Will you have a plan to
apply them to the net-next ? or I sent v4 with ACK tag.

In v3 of this series Stefano Brivio asked you to add some more curly brace
changes as feedback.  So you must address this feedback and post a new
version of the series.
