Hmmm, I don't think that is the case at all. 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.
