From 7e66016f2c65bfc1181f42274fcb7f1183ab1bb5 Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Thu, 7 Dec 2017 09:57:00 -0800 Subject: net: sched: helpers to sum qlen and qlen for per cpu logic Add qdisc qlen helper routines for lockless qdiscs to use. The qdisc qlen is no longer used in the hotpath but it is reported via stats query on the qdisc so it still needs to be tracked. This adds the per cpu operations needed along with a helper to return the summation of per cpu stats. Signed-off-by: John Fastabend Signed-off-by: David S.
