| H A D | rcu_dereference.rst | 3 PROPER CARE AND FEEDING OF RETURN VALUES FROM rcu_dereference()
8 returned from the rcu_dereference() family of primitives carry address and
9 data dependencies. These dependencies extend from the rcu_dereference()
16 freely use values from rcu_dereference(). For example, dereferencing
24 from your calls to rcu_dereference() and friends, thus keeping your RCU
27 - You must use one of the rcu_dereference() family of primitives
31 Without one of the rcu_dereference() primitives, compilers
33 different values for a single pointer! Without rcu_dereference(),
39 In addition, the volatile cast in rcu_dereference() prevents the
47 instead of rcu_dereference(). In this case, use of READ_ONCE()

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
