It would probably be better to use something else than 'rb_', because that 
prefix is already used by the red-black trees, and exported as such (eg 
"rb_next()" etc).

But at least as long as it's static, it's probably not _too_ noticeable if 
the rest of the names don't overlap. We _do_ include <linux/rbtree.h>  
almost everywhere, since we use those things in the VM, in timers etc, so 
it comes in through pretty much all headers.
