18 Without one of the rcu_dereference() primitives, compilers
20 different values for a single pointer! Without rcu_dereference(),
25 In addition, the volatile cast in rcu_dereference() prevents the

37 - You are only permitted to use rcu_dereference on pointer values.
58 subsequent accesses no longer depend on the rcu_dereference(),

91 return value from rcu_dereference(), or at least until there is some
96 if (rcu_dereference(ioc->ioc_data) == cic) {
103 With this change, the rcu_dereference() is always within an RCU
108 returned from rcu_dereference(). Instead, that pointer is just compared
109 to the cic pointer, which means that the rcu_dereference() can be replaced
