 * rcu_dereference_genl - rcu_dereference with debug checking
 * @p: The pointer to read, prior to dereferencing
 * Do an rcu_dereference(p), but check caller either holds rcu_read_lock()
 * or genl mutex. Note : Please prefer genl_dereference() or rcu_dereference()

#define rcu_dereference_genl(p)					\
	rcu_dereference_check(p, lockdep_genl_is_held())

 * genl_dereference - fetch RCU pointer when updates are prevented by genl mutex
 * @p: The pointer to read, prior to dereferencing
 * Return the value of the specified RCU-protected pointer, but omit
 * both the smp_read_barrier_depends() and the ACCESS_ONCE(), because
 * caller holds genl mutex.
