Message-ID: <20160823202412.14368.48361.stgit@john-Precision-Tower-5810> Date: Tue, 23 Aug 2016 13:24:12 -0700 From: John Fastabend <john.fastabend@...il.com> To: eric.dumazet@...il.com, jhs@...atatu.com, davem@...emloft.net, brouer@...hat.com, xiyou.wangcong@...il.com, alexei.starovoitov@...il.com Cc: john.r.fastabend@...el.com, netdev@...r.kernel.org, john.fastabend@...il.com Subject: [net-next PATCH 04/15] net: sched: provide per cpu qstat helpers The per cpu qstats support was added with per cpu bstat support which is currently used by the ingress qdisc. This patch adds a set of helpers needed to make other qdiscs that use qstats per cpu as well.
