From 97394bef5622cb32fd1e5d152251090da6c238b9 Mon Sep 17 00:00:00 2001 From: Vlad Buslov Date: Mon, 26 Aug 2019 16:44:58 +0300 Subject: net: sched: change tcf block offload counter type to atomic_t As a preparation for running proto ops functions without rtnl lock, change offload counter type to atomic. This is necessary to allow updating the counter by multiple concurrent users when offloading filters to hardware from unlocked classifiers.
