From 5d50dceccd79e5890d08adb40a538f1ac6dfe89d Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Mon, 26 Mar 2007 18:15:37 -0700 Subject: NET_SCHED: Fix ingress qdisc locking. [NET_SCHED]: Fix ingress locking Ingress queueing uses a seperate lock for serializing enqueue operations, but fails to properly protect itself against concurrent changes to the qdisc tree. Use queue_lock for now since the real fix it quite intrusive. Signed-off-by: Patrick McHardy Signed-off-by: David S.
