And in the case of the NULL pointer, there is no structure to initialize. So, rcu_assign_pointer(p, NULL) can be safely converted to RCU_INIT_POINTER(p, NULL) Signed-off-by: Monam Agarwal Signed-off-by: Eric Paris --- diff --git a/kernel/audit.c b/kernel/audit.c index c0696dcfed11..ad77d1e80895 100644 --- a/kernel/audit.c +++ b/kernel/audit.c @@ -1092,7 +1092,7 @@ static void __net_exit audit_net_exit(struct net *net) audit_sock = NULL; } - rcu_assign_pointer(aunet->nlsk, NULL); + RCU_INIT_POINTER(aunet->nlsk, NULL); synchronize_net(); netlink_kernel_release(sock); }
