I used netlink in two first versions of task_diag, but then Andy convinced me that netlink interfaces are not ideal for this case. I added him into Cс. Here is a thread with our discussion about using netlink for task_diag: https://lkml.org/lkml/2015/12/15/520 Can I ask you to read it and give your comments? It would be nice to find a way how to use netlink sockets instead of creating a new interface. Thanks, Andrew
