Bug Description
* intro
As IDR can't protect itself from the concurrent modification, place
idr_remove() under the protection of tp->lock.
* how to fix
need to backport the patch from Jianbo
"net/sched: flower: Add lock protection when remove filter handle"
https:/
* reproduce and verification
It's hard to reproduce because it is a race condition we found in k8s+ovn deployment.
