Date: Fri, 10 Apr 2015 00:53:18 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Alexander Duyck <alexander.h.duyck@...hat.com>, netdev@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jogreene@...hat.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next 9/9] ixgbe: Drop unnecessary call to rcu_barrier From: Alexander Duyck <alexander.h.duyck@...hat.com> The ixgbe driver hasn't used call_rcu to free the rings for some time now. Since that is the case the call to rcu_barrier can be dropped since calls to kfree_rcu don't require it.
