No code actually depend on specific errno values returned by vmstate_load_state. The only use of it is to check for success, and sometimes inject numeric error values into error messages in migration code. The latter is not a stopper for gradual conversion to "errp + bool return value" APIs. Big analysis of vmstate_load_state() callers, showing that specific errno values are not actually used, is done by Peter here: https://lore.kernel.org/qemu-devel/aQDdRn8t0B8oE3gf@x1.local/ Converting of vmstate_load_state() itself will follow in another series.
