Would it be possible to do this by basing it off of one of Linus's tags,
and doing the merge and conflict resolution in your tree before it gets to
Linus?

That way we can pull in that clean branch without having to pull in
anything else from BPF. I believe Linus prefers this over having tracing
having extra changes from BPF that are not yet in his tree. We only need
these particular changes, we shouldn't be pulling in anything specific for
BPF, as I believe that will cause issues on Linus's side.
