This is fine by me - there's nothing in the iproute2 patches that depends on any particular version of libbpf newer than 0.1.0 (that was the whole point), so it's just a matter of when you guys want to merge it. > It would be good for others (Jesper, Toke, Jiri) to run their own > testing as well. I'll do some manual testing, and once we get this into RHEL it'll be part of automated testing there as well. The latter may take a while, though, so don't count on it for any initial verification... -Toke
