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)
