This reverts commit 8a7b31d545d3a15f0e6f5984ae16f0ca4fd76aac. This patch results in some qemu test failures, specifically xilinx-zynq-a9 machine and zynq-zc702 as well as zynq-zed devicetree files, when trying to boot from USB drive.

This bug is marked as fixed by commit: net: core: netlink: add helper refcount dec and lock function net: sched: add helper function to take reference to Qdisc net: sched: extend Qdisc with rcu net: sched: rename qdisc_destroy() to qdisc_put() net: sched: use Qdisc rcu API instead of relying on rtnl lock But I can't find it in the tested trees[1] for more than 90 days. Is it a correct commit? Please update it by replying: #syz fix: exact-commit-title Until then the bug is still considered open and new crashes with the same signature are ignored.
