Date: Mon, 08 Sep 2014 16:43:13 -0700 (PDT) From: David Miller <davem@...emloft.net> To: willemb@...gle.com Cc: netdev@...r.kernel.org, eric.dumazet@...il.com Subject: Re: [PATCH net-next] inet: remove dead inetpeer sequence code From: Willem de Bruijn <willemb@...gle.com> Date: Mon, 8 Sep 2014 19:08:34 -0400 > inetpeer sequence numbers are no longer incremented, so no need to > check and flush the tree. The function that increments the sequence > number was already dead code and removed in in "ipv4: remove unused > function" (068a6e18). Remove the code that checks for a change, too. > > Verifying that v4_seq and v6_seq are never incremented and thus that > flush_check compares bp->flush_seq to 0 is trivial. > > The second part of the change removes flush_check completely even > though bp->flush_seq is exactly !0 once, at initialization. This > change is correct because the time this branch is true is when > bp->root == peer_avl_empty_rcu, in which the branch and > inetpeer_invalidate_tree are a NOOP. > > Signed-off-by: Willem de Bruijn <willemb@...gle.com> Applied, thanks a lot. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
