Urgh. Please, no. That is well impossible to debug. Can you please open-code it to demonstrate where the difference to the current (and my fixed) versions is? I'm still not clear where the problem is once we applied both patches.For example assume the list has three path, and all path is not NVME_ANA_OPTIMIZED: head->next = ns1; ns1->next = ns2; ns2->next = head; old->next = ns2;
And this is where I have issues with. Where does 'old' come from? Clearly it was part of the list at one point; so what happened to it?
