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 --- kernel/audit.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/audit.c b/kernel/audit.c index 3392d3e..bc240ba 100644 --- a/kernel/audit.c +++ b/kernel/audit.c @@ -1087,7 +1087,7 @@ 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); } -- 1.7.9.5
