Jarek Poplawski e0f7cb8c8c ipv4: Fix fib_trie rebalancing ... While doing trie_rebalance(): resize(), inflate(), halve() RCU free tnodes before updating their parents. It depends on RCU delaying the real destruction, but if RCU readers start after call_rcu() and before parent update they could access freed memory. It is currently prevented with preempt_disable() on the update side, but it's not safe, except maybe classic RCU, plus it conflicts with memory allocations with GFP_KERNEL flag used from these functions. This patch explicitly delays freeing of tnodes by adding them to the list, which is flushed after the update is finished.
