Subject: batman,rcu: convert call_rcu(softif_neigh_free_rcu) to kfree_rcu
X-Git-Tag: v3.12-rc1~6111^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8e3572cff70ee19a0a1f2e2dde0bca0b7c8b54dc;p=kernel%2Fkernel-generic.git

batman,rcu: convert call_rcu(softif_neigh_free_rcu) to kfree_rcu

The RCU callback softif_neigh_free_rcu() just calls kfree(), so we can
use kfree_rcu() instead of call_rcu().
