io_uring_cmd_import_fixed_vec() is a cmd helper around vectored registered buffer import functions, which caches the memory under the hood. The lifetime of the vectore and hence the iterator is bound to the request. Furthermore, the user is not allowed to call it multiple times for a single request.
