Introduction of qdisc->running seqcount added lockdep false positives. While chasing the bug, it came to me that we had a lot of copies of the same stuff in virtual drivers.
This patch series has the qdisc->running fix (considers that a trylock is attempted in lockdep terminology), and adds a generic helper so that we no longer have to patch many virtual drivers when a new per-device or per-qdisc lock is added. Thanks to David Ahern for reporting the issue and testing my patches :) Eric Dumazet (5): net: sched: fix qdisc->running lockdep annotations net: add netdev_lockdep_set_classes() helper net: vrf: call netdev_lockdep_set_classes() net: macvlan: call netdev_lockdep_set_classes() net: ipvlan: call netdev_lockdep_set_classes() drivers/net/bonding/bond_main.c | 24 +----------------------- drivers/net/ipvlan/ipvlan_main.c | 22 +--------------------- drivers/net/macvlan.c | 11 +---------- drivers/net/ppp/ppp_generic.c | 6 +----- drivers/net/team/team.c | 21 +-------------------- drivers/net/vrf.c | 2 +- include/linux/netdevice.h | 17 +++++++++++++++++ include/net/sch_generic.h | 6 +++++- net/bluetooth/6lowpan.c | 15 +-------------- net/ieee802154/6lowpan/core.c | 16 +--------------- net/l2tp/l2tp_eth.c | 6 +----- net/sched/sch_generic.c | 4 ++-- 12 files changed, 33 insertions(+), 117 deletions(-) -- 2.8.0.rc3.226.g39d4020
