Subject: net,rcu: convert call_rcu(ip_mc_list_reclaim) to kfree_rcu()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=42ea299d3f1941f8c3dbc1fe031d682f8ad45005;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

net,rcu: convert call_rcu(ip_mc_list_reclaim) to kfree_rcu()

The rcu callback ip_mc_list_reclaim() just calls a kfree(),
so we use kfree_rcu() instead of the call_rcu(ip_mc_list_reclaim).
