Doc: Fix wrong API example usage of call_rcu().
Jesper Dangaard Brouer [Sun, 29 Mar 2009 23:03:01 +0000 (23:03 +0000)]
At some point the API of call_rcu() changed from three parameters
to two parameters, correct the documentation.

One confusing thing in RCU/listRCU.txt, which is NOT fixed in this patch,
is that no reason or explaination is given for using call_rcu() instead of
the normal synchronize_rcu() call.
