Merge branch 'net-sched-fix-race-conditions-in-mini_qdisc_pair_swap'
Peilin Ye says:
====================
net/sched: Fix race conditions in mini_qdisc_pair_swap()
These 2 patches fix race conditions for ingress and clsact Qdiscs as
reported [1] by syzbot, split out from another [2] series (last 2 patches
of it). Per-patch changelog omitted.
Patch 1 hasn't been touched since last version; I just included
everybody's tag.
Patch 2 bases on patch 6 v1 of [2], with comments and commit log slightly
changed. We also need rtnl_dereference() to load ->qdisc_sleeping since
commit d636fc5dd692 ("net: sched: add rcu annotations around
qdisc->qdisc_sleeping"), so I changed that; please take yet another look,
thanks!
Patch 2 has been tested with the new reproducer Pedro posted [3].
