Without entering such troll subjects, the patent issue completely kills using
RCU outside of Linux. RCU is patented IBM with special licence to use in Linux
only, as far as i remember. Due to the history of IBM it would be suicidal
Linux-only doesn't exist per-se, since linux is GPL and any GPL code
can be remixed without problems. So, the question would be if it's ok
to remix GPL with DFBSD license (which probably doesn't)
Well, there is a difference between copyright-law and patent-law. The
code is protected by GPL (which is not compatible with BSD-licenses, and
I doubt that we'll ever see any GPL in the kernel). The algorithm (or
technique or whatever) is protected by a patent and you need a special
license to use it, which, as far as I know, IBM have not given to anyone
but Linux.
