From 06f5553e0f0c2182268179b93856187d9cb86dd5 Mon Sep 17 00:00:00 2001 From: Yunsheng Lin Date: Tue, 3 Aug 2021 18:58:21 +0800 Subject: net: sched: fix lockdep_set_class() typo error for sch->seqlock According to comment in qdisc_alloc(), sch->seqlock's lockdep class key should be set to qdisc_tx_busylock, due to possible type error, sch->busylock's lockdep class key is set to qdisc_tx_busylock, which is duplicated because sch->busylock's lockdep class key is already set in qdisc_alloc(). So fix it by replacing sch->busylock with sch->seqlock. Fixes: 96009c7d500e ("sched: replace __QDISC_STATE_RUNNING bit with a spin lock") Signed-off-by: Yunsheng Lin Signed-off-by: David S.
