McKenney" Commit d8169d4c (Make __kfree_rcu() less dependent on compiler choices) created a macro out of an inline function in order to avoid build breakage for certain combinations of gcc flags. Unfortunately, it also converted a kfree_call_rcu() to a call_rcu(), which made the rcu_data structure's ->qlen_lazy field lose counts. This commit therefore changes the call_rcu() back to kfree_call_rcu(). Signed-off-by: Paul E. McKenney Signed-off-by: Paul E.
