The bool is essentially an extension of KVM_REQ_GET_NESTED_STATE_PAGES, I think it makes sense to clear the flag whenever KVM_REQ_GET_NESTED_STATE_PAGES is cleared.
So in vcpu_enter_guest?
Another thing that's not obvious is the required ordering between KVM_SET_SREGS2 and KVM_SET_NESTED_STATE. AFAICT it's not documented, but that may be PEBKAC on my end. E.g. what happens if walk_mmu == &root_mmu (L1 active in targte KVM) when SET_SREGS2 is called, and_then_ KVM_SET_NESTED_STATE is called?
Either ordering should work. Paolo
