- * Cpumask for callback CPUs. It should be

- * cb_cpumask is protected by RCU. This fact prevents us from
- * using cpumask_var_t directly because the actual type of
- * cpumsak_var_t depends on kernel configuration(particularly on
- * CONFIG_CPUMASK_OFFSTACK macro). Depending on the configuration
- * cpumask_var_t may be either a pointer to the struct cpumask
- * or a variable allocated on the stack. Thus we can not safely use
- * cpumask_var_t with RCU operations such as rcu_assign_pointer or
- * rcu_dereference. So cpumask_var_t is wrapped with struct
- * pcrypt_cpumask which makes possible to use it with RCU.
