Subject: [PATCH 5/8] ipv6: xfrm6_tunnel.c: Use built-in RCU list checking
Date: Fri, 27 Mar 2020 09:10:04 +0100	[thread overview]
Message-ID: <20200327081007.1185-6-steffen.klassert@secunet.com> (raw)
In-Reply-To: <20200327081007.1185-1-steffen.klassert@secunet.com>

From: Madhuparna Bhowmik <madhuparnabhowmik10@gmail.com>

hlist_for_each_entry_rcu() has built-in RCU and lock checking.

Pass cond argument to list_for_each_entry_rcu() to silence
false lockdep warning when CONFIG_PROVE_RCU_LIST is enabled
by default.
