From 6dc14dc40a1d1dafd8491c349b5f3e15aabc4edb Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 14 Nov 2017 06:27:12 +0000 Subject: [PATCH] openvswitch: Using kfree_rcu() to simplify the code The callback function of call_rcu() just calls a kfree(), so we can use kfree_rcu() instead of call_rcu() + callback function.
