From 1aee6cc2a5193aa9963ea49b0d452723c1d493d8 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 16 Dec 2013 14:05:50 +0800 Subject: [PATCH] net/hsr: 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.
