[RELEASE] Userspace RCU library (liburcu) 0.2

[Mathieu Desnoyers]

Hi,

Here is a 0.2 version of the urcu library. It should clarify usage of

rcu_cmpxchg_pointer
rcu_xchg_pointer
rcu_set_pointer

which are the recommended primitives to deal with pointers.
rcu_assign_pointer(ptr, new) is provided as compatibility layer with the
Linux kernel semantic, but note that its semantic for the first
parameter is IMHO odd and differs from rcu_{cmpxchg,xchg,set}_pointer.

Thanks,

Mathieu
