#define genl_dereference

rcu_dereference_protected(p, lockdep_genl_is_held())

genl_dereference - fetch RCU pointer when updates are prevented by genl mutex : 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.

rcu_dereference_check(p, lockdep_genl_is_held())

rcu_dereference_genl - rcu_dereference with debug checking : 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()
