From: Dong Chenchen <dongchenchen2@huawei.com> This series backports the CVE-2026-72390 fix for the OLK-5.10 kernel. Patch 1 introduces a per-master slaves_lock spinlock and RCU accessors around the master->slaves list to prevent concurrent mutation and use-after-free in the TEQL qdisc. Patch 2 is a follow-up that switches the rcu/spin primitives in teql_master_xmit() from the _bh variants to plain variants, since ndo_start_xmit is already called with BH disabled. Both patches preserve the original author sign-offs and add the adapter signature.
