Will contact upstream.
Yeah, if there's no MODULE_LICENSE then a module is assumed to be
proprietary. The ZSMALLOC symbols are exported with EXPORT_SYMBOL_GPL,
so not available to proprietary modules. So this will currently only
work if you have both built-in!
The zsmalloc module is also lacking MODULE_LICENSE, and has great
comments like:
/*
* If this becomes a separate module, register zs_init with
* module_init, and remove this block
*/
