From 3fe6b49e2f8adc61fef9a22ecc0c3565f9ea468d Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Tue, 2 Dec 2014 18:00:33 +0100 Subject: [PATCH] net_sched: cls_bpf: remove faulty use of list_for_each_entry_rcu rcu variant is not correct here. The code is called by updater (rtnl lock is held), not by reader (no rcu_read_lock is held). Signed-off-by: Jiri Pirko ACKed-by: Jamal Hadi Salim Acked-by: Daniel Borkmann Signed-off-by: David S.
