Subject: net,act_police,rcu: remove rcu_barrier()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=75ef0368d182785c7c5c06ac11081e31257a313e;p=openwrt%2Fstaging%2Fblogic.git

net,act_police,rcu: remove rcu_barrier()

There is no callback of this module maybe queued
since we use kfree_rcu(), we can safely remove the rcu_barrier().
