What's the difference between synchronize_rcu() and rcu_barrier() (new function 
used only by reiser4 code)? From the scant documentation it seems like they do 
the same thing.

I'm now happily running 2.6.13-rc4-rt-v0.7.52-14-reiser4 which I compiled by adding

#define rcu_barrier synchronize_rcu

so there must not be that much difference =) (at least on UP, that is).
