I know this is version 9 of the patch, so I'm sorry for the late comment, but I
have to ask: Why re-invent this wheel?  There are already several Userspace RCU
libraries that are mature and carried by Linux and BSD distributions.  Why would
we throw another one into DPDK instead of just using whats already available,
mature and stable?
