additionally, please apply the patch https://github.com/urcu/userspace-rcu/commit/3214608619eac09e9c0ab1ea9a1a36bd1b85c18d. this patch significantly decreases idle CPU usage of knotd, which I think justifies its inclusion, considering that as far as I know, knot2 is the only reverse dependency of liburcu currently in ports.
