McKenney <paulmck@xxxxxxxxxxxxxxxxxx> CommitDate: Tue, 21 Feb 2012 09:03:31 -0800 ipv4: Convert call_rcu() to kfree_rcu(), drop opt_kfree_rcu() Because opt_kfree_rcu() just calls kfree(), all call_rcu() uses of it may be converted to kfree_rcu(). This permits opt_kfree_rcu() to be eliminated. Signed-off-by: Paul E. McKenney <paul.mckenney@xxxxxxxxxx> Signed-off-by: Paul E. McKenney <paulmck@xxxxxxxxxxxxxxxxxx> Acked-by: David S.
