3 Most of the time, you can use values from rcu_dereference() or one of
11 o You must use one of the rcu_dereference() family of primitives
15 Without one of the rcu_dereference() primitives, compilers
17 different values for a single pointer! Without rcu_dereference(),
22 In addition, the volatile cast in rcu_dereference() prevents the
28 o You are only permitted to use rcu_dereference on pointer values.
49 subsequent accesses no longer depend on the rcu_dereference(),
52 Of course, if "p" is a pointer from rcu_dereference(), and "a"
55 the rcu_dereference(), thus maintaining proper ordering.

91 if (rcu_dereference(ioc->ioc_data) == cic) {
98 With this change, the rcu_dereference() is always within an RCU
103 returned from rcu_dereference(). Instead, that pointer is just compared
104 to the cic pointer, which means that the rcu_dereference() can be replaced
