Date: Tue, 27 Jul 2021 21:14:13 +0800 From: xiangxia.m.yue@...il.com To: xiyou.wangcong@...il.com, netdev@...r.kernel.org Cc: Tonghao Zhang <xiangxia.m.yue@...il.com> Subject: [net-next] qdisc: add new field for qdisc_enqueue tracepoint From: Tonghao Zhang <xiangxia.m.yue@...il.com> qdisc_enqueue tracepoint can work with qdisc:qdisc_dequeue to measure packets latency in qdisc queues. Add a new field txq for it, then we can retrieve more info.
