FYI, I've converted the code to a single level union, but the result is questionable as the subop that selects which structure in the union is the first element of each structure. This also required some messy work in the CONFIG_COMPAT in tmh_get_tmemop_from_client, but it compiles now and I can proceed with debugging.
