commit bfc2560563586372212b0a8aeca7428975fa91fe upstream. This is a follow up of commit ea3274695353 ("net: sched: avoid duplicates in qdisc dump") which has fixed the issue only for the qdisc dump. The duplicate printing also occurs when dumping the classes via tc class show dev eth0 Fixes: 59cc1f61f09c ("net: sched: convert qdisc linked list to hashtable") Signed-off-by: Maximilian Heyne <mheyne@amazon.de> Signed-off-by: David S.
