any chance these patches can still make into this release considering
they were ready back in December ?
We have few followups for them and if we don't get them via Linus's tree
into net-next/bpf-next we cannot really proceed further.
The other option would be to cherry-pick them into bpf-next/net-next,
but also a bit scary due to potential conflicts?

Thanks!
