From 7790614616458b6dd3d90652acfa6b7443ee7041 Mon Sep 17 00:00:00 2001 From: Madhuparna Bhowmik Date: Wed, 19 Feb 2020 01:24:25 +0530 Subject: [PATCH] meter.c: Use built-in RCU list checking 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. Signed-off-by: Madhuparna Bhowmik Signed-off-by: David S.
