From b55071eb6011413af3b9c434ae77dea8832069c8 Mon Sep 17 00:00:00 2001 From: Lai Jiangshan Date: Fri, 18 Mar 2011 12:02:47 +0800 Subject: [PATCH] net,rcu: convert call_rcu(xps_dev_maps_release) to kfree_rcu() The rcu callback xps_dev_maps_release() just calls a kfree(), so we use kfree_rcu() instead of the call_rcu(xps_dev_maps_release).
