[PATCH rcu 01/10] rcu: Use hlist_nulls_next_rcu() in hlist_nulls_add_tail_rcu()
From: Paul E. McKenney
Date: Wed Jan 04 2023 - 19:23:27 EST
From: Zhao Mengmeng <zhaomengmeng@xxxxxxxxxx>
In commit 8dbd76e79a16 ("tcp/dccp: fix possible race
__inet_lookup_established()"), function hlist_nulls_add_tail_rcu() was
added back, but the local variable *last* is of type hlist_nulls_node,
so use hlist_nulls_next_rcu() instead of hlist_next_rcu().
