Subject: net,rcu: convert call_rcu(__leaf_info_free_rcu) to kfree_rcu()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bceb0f4512d448763fe98c9f37504c98bbebbed6;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

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

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