They are, ISTM, claiming that the RCU code contributed to Linux is derived from SysV. That is, they are making a contractual and copyright cliam, I think. It would not be hard to write a non-derived implementation. The more important issue is the Patent issue, but I think there are ways to get IBM to grant royalty free access, after all, they have done it for Linux.
