When this is ready, I'll be happy to inform Linus on the pull request
that you NACKed it, if you are still against it by then. He's Cc'd on
this conversation now. But you left out any technical reason for the
NACK. You basically just said "I don't see how this is useful to me".
That's not a valid reason for a NACK.

Gabriele will be presenting this work at Linux Plumbers[1]. This will
not be going in before then. I would strongly recommend attending
Gabriele's session and we can then go into the technical arguments
about the use of BPF there. If you bring up valid technical reasons
against it, then we will either work with you to solve those technical
issues, and if they can't be solved then sure, it will not go in. But
if it's just your opinion about the work not being useful to you, then
I will push this forward, as it is very useful to others.

Cheers,
