#define rcu_dereference_rtnl (   p)    rcu_dereference_check(p, lockdep_rtnl_is_held())

rcu_dereference_rtnl - 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 RTNL. Note : Please prefer rtnl_dereference() or rcu_dereference()

Definition at line 36 of file rtnetlink.h.

#define rtnl_dereference (   p)    rcu_dereference_protected(p, lockdep_rtnl_is_held())

rtnl_dereference - fetch RCU pointer when updates are prevented by RTNL : 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 RTNL.
