Subject: [PATCH] xfrm: fix rcu_read_unlock usage in xfrm_local_error
Date: Tue, 13 Mar 2018 17:26:07 +0900 [thread overview]
Message-ID: <20180313082607.19409-1-ap420073@gmail.com> (raw)
In the xfrm_local_error, rcu_read_unlock should be called when afinfo
is not NULL. because xfrm_state_get_afinfo calls rcu_read_unlock
if afinfo is NULL.
