| H A D | rcu_dereference.rst | 3 PROPER CARE AND FEEDING OF RETURN VALUES FROM rcu_dereference()
31 Without one of the rcu_dereference() primitives, compilers
96 p = rcu_dereference(gp)
111 obtained from rcu_dereference(). For example::
113 p = rcu_dereference(gp);
121 p = rcu_dereference(gp);
135 it is safe to compare pointers from rcu_dereference()
148 used in place of rcu_dereference(). In most cases,
258 p = rcu_dereference(gp2);
319 p = rcu_dereference(gp2);

| H A D | lockdep-splat.rst | 9 misuses of the RCU API, most notably using one of the rcu_dereference()
70 if (rcu_dereference(ioc->ioc_data) == cic) {
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
